Where have all the American children gone?
The Emperor’s New Clothes
‘FAIRways’ for All
Kerry Packer is incidental to this post on golf.
“There is a little bit of the whore in all of us, gentlemen. What is your price?”
When Kerry Packer reportedly delivered that line during negotiations with the Australian Cricket Board, he wasn’t merely bargaining for television rights — he was detonating a revolution. What followed, reshaped cricket forever. The game leapt from stately grounds and private clubs into living rooms, into prime time… into the bloodstream of nations. Cricket became spectacle. It became aspiration. Above all, and most importantly, it became accessible. Before Packer, cricket belonged to the privileged few. After him, it belonged to the masses.
Like cricket, golf was introduced to India by the British and has been played here for nearly 200 years. But unlike cricket, golf has never quite had its Kerry Packer.
The sport has always worn an expensive reputation like a blazer badge. The cost of equipment; the vast acreage required; the manicured greens; the membership walls — have kept the game away from the common man. In India especially, it signals status before it signals sport. A golfer is presumed to be affluent, uniformed, bureaucratic — or a caddie who caught lightning in a bottle.
But revolutions rarely announce themselves with television contracts. Sometimes, they begin quietly — with one believer.
India’s golf revolution seems round the corner.
Wing Commander Arun Kumar Singh — “AK” to friends — is no corporate magnate. An Indian Air Force veteran, former Parachute Jump Instructor, mountaineer, and the founding Commandant of the IAF’s elite Garud Special Force — AK’s life has been defined by discipline and audacity.
He first swung a golf club at the National Defence Academy in 1978 — he thanks his buddy, Rahul Bhardwaj for introducing him to the game. But it wasn’t until the late 1990s, while serving as Secretary of the Air Force Sports Complex, that his relationship with the game deepened into a mission. He upgraded the golf course, introducing sand-based greens in line with USGA recommendations. The improvements were technical — the impact, transformative. Participation surged.
Where others saw turf, AK saw possibility. Through keen observation, AK had discovered a pattern. India’s golf champions (particularly Army children and some caddies) often shared a common denominator: access. For ‘Army kids’, access to courses in cantonments was easy. Likewise, some caddies were lucky to get similar access to courses like Delhi Golf Club and Royal Calcutta Golf Club which enabled them to achieve excellence.
So, he chose to create access.
His stint at Golden Greens became a laboratory for inclusivity. Amateurs (including juniors) in the IGU order of merit were allowed to compete; sometimes, free of charge. Professionals from the PGTI and WGAI were facilitated likewise. In the early years, PGTI, WGAI and Albatross began conducting their events there, often at highly concessional rates; and at times, free. In AK, budding players found not just a host, but a patron.
Later, as the Director General of the Indian Golf Union, AK widened the map — conducted feeder tours across zones. He took IGU tournaments beyond the usual metros — to Shillong, Visakhapatnam, Cochin etc. New geographies; new dreams!
The most radical strokes were, however, played off the course. AK took Rotary Club on board to fund golf at the school level. In a heart-warming initiative, he joined hands with “RAYS – Asha ki ek Kiran,” an NGO to introduce the game to HIV-positive children who had been (almost) rejected by their near and dear ones. It was a ‘simply’ noble cause — “To give those children an identity and self-worth through golf.” AK thanks Preetam Saikia and his team who toil to turn ordinary children into promising golfers.
AK’s Ultimate Foundation (UF) has opened doors for children from less privileged backgrounds. In collaboration with Golden Greens, UF has been selecting young golfing talents from modest backgrounds; some have already begun playing on the national circuit. Thanks to another enthusiast friend, Wing Commander Pradeep Bagmar, government school students in Nashik and Niphad were given a chance to swing a club at Riverside Golf Course — many for the first time in their lives. An enthusiastic and dedicated Ms Navita Mansingh (Secy, UF), he says, keeps UF going.
The 23-year-old Green Keepers and Superintendents Association of India is the body of turfcare professionals who work behind the scenes to keep the golf courses in good condition and suitable for playing. The Association focuses on education about turfcare and regularly conducts programs/seminars by inviting external and in house domain experts. As the current President of the Association, AK has recently promoted and supported a certification program for the professionals in collaboration with Protouch Sports and George College of Kolkata.
Today, as advisor to “72 The League” — India’s first professional golf league — AK stands at another inflection point. With icons like Kapil Dev, Samant Sikka, Amit Kharbanda (Game of Life), Joy Bhattacharya (ESPN fame), Shouvik Roy and Aditya Ghosh lending their weight, the league promises to blend youth and experience, amateurs and professionals, teenagers and veterans in their sixties.
Success of “72 The League” will do for golf what Packer did for cricket — minus the provocation, minus the profiteering. It’ll popularise the game and shatter the myth of the game’s inaccessibility. Here, and now, AK Singh is not selling television rights; he is only creating opportunity for enthusiasts who would otherwise never step onto a fairway.
Revolutions do not always roar. Sometimes, they tee off quietly at dawn. And sometimes, all it takes to change a sport is a man who refuses to believe it belongs only to the privileged few.
PS: Passionate about popularising the game, AK is a moving, living encyclopaedia of golf; a repository of interesting stories. His knowledge of the history of the game is profound. All one needs to do is — goad the otherwise quiet man, into speaking.
I (really) saw God!
It is true as true can be.
Now, this not that time of the day when I am usually engrossed in intellectual discussions with friends after downing a few Paul Johns, or Old Monks, or some wine — or a “Green ON! Go!” for that matter. That I saw God is not a figment of my imagination after a few drinks. It really happened.
Before I proceed, a word about God, godliness, and my stand on that subject.
I am neither an atheist nor a believer. But, sometimes I do flaunt Rudraksh beads; I feel they go well with my baldness and round-rimmed glasses. Occasionally, I also apply chandan (sandalwood paste) on my forehead; it is so soothing. The beads and the chandan ka tika—together, they give me a rather cool, saintly look. That is my belief. But my dear wife urges me to discard them. “This kind of symbolism is meaningless; be a good human being and people will see God in you,” she says admonishingly, so I give up the pretence.
With or without saintliness and godliness, life goes on.
Yet, sometimes in this God’s Own Country, I wonder if HE/SHE (THEY) really exist. What do THEY look like? Multiple heads and arms? Riding a tiger, a mouse, an elephant, or a swan? I got my answer when I visited Ranthambore recently.
It was a family holiday—nearly twenty of us. The night before, at Juna Mahal (the resort), we had great time — star-gazing, folk songs and music and local cuisine. We were all set to embark on a tiger safari the next afternoon. Since the morning was free, some of us decided to visit the Amareshwar Mahadev Temple nearby. Each one on board had an agenda to be met at the temple. I guess most were going there to seek “special” blessings. As for me, I was eager to discover the physics behind the perpetual trickle of water falling on the Shivling in that small temple carved inside a rock—a cave of sorts; Lord Shiva’s blessings would be a bonus.
It was mandatory to leave the cars at a gate about two kilometres from the temple. A jeep meant to ferry visitors, took us to the foot of the hill on which the temple was situated. Thereafter, it was about a kilometre and a half of gentle climb through rocky terrain. We were warned to remain in a group, as tigers had been spotted in the area in the past.
I belong to Ujjain, known for its temples—Mahakaleshwar, in particular. When I realised that, like the Mahakaleshwar Temple, the Amareshwar Mahadev Temple is dedicated to Lord Shiva, I began looking for similarities, which were aplenty—such as, the Shivling and a small water tank for people to take a dip. But there was a striking difference that caught my eye. The 1.5 km walkway to the temple was clean beyond imagination. This was in sharp contrast to the litter one sees around Mahakaleshwar and other temples. I attributed the exceptional cleanliness to the relatively (much) lower footfall at that site, and concluded the dialogue within.
The temple surroundings were clean too. And ah, the serenity! It was a cherished world far from the humdrum of where each one of us had come from—Noida, in my case. One had to prostrate oneself to get a close darshan of the Shivling. The constantly trickling thin stream of water from the rocks above the Shivling evoked reverence and amazement. It had been dripping for many years. We spent a blissful half hour at the temple before heading back. The return trek was uneventful yet fun.
While driving back in the rickety jeep, we crossed a man dressed in a saffron half-kurta and a white dhoti. With long hair, a beard, and a cloth bag dangling from his hand, he looked like a typical sadhu. I thought he was one of the caretakers on his way to the temple.
“This old man is walking alone to the temple. Isn’t he afraid of the tigers?” I asked the driver of our jeep out of sheer curiosity.
I listened in disbelief to what the driver told us about the man. “That man in saffron is Ganesh. He is the son of one Ramchandra Verma and lives in a nearby village. He has been walking to the temple and back every day for the last forty years. On his way up and down, he collects litter thrown around by devotees. We owe the cleanliness of this place to this one man. He does it selflessly, and with devotion; doesn’t charge a paisa. He lives on whatever he earns by tilling his small piece of land.”
When I turned back, I saw the man in the distance, a halo around him—the kind we see in pictures of gods and saints. I had no doubt; I had caught a glimpse of a living GOD.
Postscript
No regret that we didn’t spot a tiger that day.
Last week, when I got an opportunity to visit Ranthambore again, I grabbed it with both hands. While another tiger safari was the loudly proclaimed agenda, somewhere at the back of my mind was a strong desire to cross paths with the same god. Sadly, this time I missed both—the tiger and the god.
If, and when, I revisit Ranthambore, it will be with the primary motive of meeting Ganesh — all else, will be secondary.
“Chanakya”
“Chanakya” as the real Chanakya could possibly have been!
My revered theatre friend, Shri Ashok Banthia, rekindled my love for the stage when he invited me to work with him on the play Maha Param Veer two years ago. The production was staged in Udaipur, Jaipur, and Bhopal, and is expected to travel to other state capitals as well.
Recently, thanks to Ashokji, I had my first glimpse into the beautiful world of the National School of Drama (NSD). I was awestruck, to say the least. As is often my habit of wishing I could go back in time to pursue unfulfilled dreams, I found myself longing to study drama at NSD. That renewed desire arose from the stellar performances I witnessed yesterday.
The play was Chanakya.
All of us Indians have grown up hearing stories of Chanakya and Chandragupta Maurya. Honestly, those stories seldom inspire awe anymore. However, this Chanakya—researched and scripted over four years—felt fresh and intellectually invigorating. Having been staged more than 1,700 times, it’s no surprise that the actors have come to live and breathe their roles. Watching them, I couldn’t help but wonder if the real Chanakya, Amatya Rakshas, and Chandragupta Maurya could have expressed themselves half as powerfully. No exaggeration intended!
The team led by Manoj Joshi (as Chanakya) and Ashok Banthia (as Amatya Rakshas) delivered a sterling performance. The dialogues were powerful and passionate, complemented by excellent costumes, lighting, sound, and music—every element of the production was par excellence. Time seemed to fly, and before I knew it, the play was over.
Beyond its artistic brilliance, the play reintroduces Indian history in a way that leaves a lasting impact. Those who watch it—especially those involved in running the country—will carry pearls of wisdom passed on by the real Chanakya through Manoj and Ashok’s portrayals.
We often judge a film or play by whether it’s worth our time. My conclusion? Watching Chanakya was worth more than a dozen of the best films or OTT series combined.
When I received a warm, friendly hug from Shri Ashok Banthia after the performance, I couldn’t hold back my hidden desire. I requested him, “Sir, please accept me as your pupil. If nothing else, I’ll cherish the role of a tree or a lamp-post beside which you stand and mesmerize audiences.”
Kudos to Manoj, Ashok, and the entire Chanakya team!
Delhi’s Dirty Air: Why Quick-fixes don’t work?
Every dust particle removed ‘permanently‘ from the air, is a dust particle less in Delhi’s lungs.
Delhi has done much and is contemplating more to rid its air of menacing particulate matter. Atomisers, sprinklers, mechanical road sweepers, smog towers and now, cloud seeding, is being resorted to clean the air. Regardless of the cost, the effectiveness of these methods has been, at the best, marginal.
Except smog towers and mechanical road sweepers, all the other methods (including, the much talked about cloud seeding) of removing particulate matter from the air are either temporary, or have the tendency to transfer the problem from one locality to another. The water (sprayed or sprinkled) supresses the particulate matter temporarily. The dust particles when brought down at one place by water, first stick to the road surface and then cling to the wheels of the passing vehicles, and are carried to other parts of the city. When the water evaporates and the wheels become dry, the particles are released back into the air. Thus, the dust from Mayur Vihar gets transported to Lajpat Nagar; that from Lajpat Nagar, to Sarojini Nagar, and so on and so forth.
Old particles remain in circulation and new get added from different sources. The relief, if at all, is temporary and psychological.
Talking of smog towers. Studies suggest that they make a marginal difference. The smog tower at Connaught Place was installed at an approximate cost of $2.5 million (nearly ₹ 21 Crores). Where the tower stands, its efficiency is 50%; at 50 metres, it is 30%; and at 500 metres it is just 10%. If the filters are improperly sealed; they allow dusty air to by-pass them. As per some estimates, Delhi would need 2.5 million such smog towers to clean its air. The likely cost will be close to $20 billion, about 2.5 times the Delhi State budget for 2021. Numbers speak!
It is noteworthy that Beijing and Shanghai have abandoned large-scale smog towers because of limited success.
Suppressing dust particles by causing artificial rain (through cloud seeding), likewise, will have temporary effect—the dust particles will remain tethered to the earth’s surface only as long as it is wet. If by some chance, the rain is heavy, poor drainage will cause traffic snarls. In effect, we’ll rob Peter to pay Paul—if not the lungs, the roads will get clogged. Delhiites will pay for both.
Is there a way out?
Of course, there is one! It follows the principle: capture particulate matter and prevent it from getting back into circulation. It is as simple as it sounds.
This can be achieved as follows:
- Polluted air (laden with particulate matter) is directed on to moist screens, or is passed through specially designed ducts whose walls are moist.
- The wet surfaces/ ducts ‘trap’ particulate matter and let go of cleaner air—devoid of particulate matter.
- These wet surfaces and ducts are continuously cleaned by running water, or still better, water jets. The running water takes away the particulate matter with it and deposits it into a sump. Thus, the wet surface always remains clean and ready to ‘trap’ more particles.
- From the sump, the particulate matter is removed continuously by decantation/ filtration and the water is reused.
- The particulate matter thus removed is disposed of in a way that it doesn’t get into circulation again.
Using this principle, simple inexpensive static and mobile contraptions can be made to very effectively ‘capture’ particulate matter and consign them to their graves.
Yours truly, confident of the effectiveness of this method, had written to the authorities who matter. There must have been some communication gap, because the response was on these lines: “If you have a problem, please connect with the concerned department. Thank you for visiting the website.”
When I presented this idea to budding engineers (college students whom I lecture sometimes), they responded favourably and expressed their desire to take up projects on these lines. But very soon, they backed off for they had graver concerns—examinations and placement interviews.
Thus, what I thought was a cost-effective practical solution to Delhi’s woes got stored into some less frequently visited corner of my mind.
Then this childhood friend, while playing golf, rekindled the subject discussion, “It is a desperate situation now. The AQI has risen to alarming levels. It is still rising. The concern is high. Yours seems to be a workable solution. Why don’t you write to Delhi Govt?”
Going by my past experience, I was disinclined to go through the grind again. But then, the thought came to share the idea in a blogpost which passes more eyes.
So here it is.
I share this post in a hope that someone, somewhere, turns this simple idea into a real solution for Delhi’s lungs. Among the beneficiaries will be my better half and some of my dear friends who are occasionally forced to use inhalers and nebulisers for respite.
Author’s Notes: This method of removing particulate matter from the air, ‘for good‘, can be implemented in numerous and innovative ways. Before posting this article, I shared my thoughts on the subject with my BITSIAN brother, Sumit Chordia, and lo and behold, he came up with umpteen suggestions not only to trap the rogue particles flying in the air but also to check pollution at source. Likewise, I invite my readers to share what comes to mind. Eventually some idea, will work.
Comments & Feedback
- Air Commodore Meenu Vania, SC, VM: Any idea is better than no idea 🙏 In your case what you propose seems a workable solution and deserves a trial. I also have a point of view 👍I propose we tackle the known sources of air pollution ie construction activities, vehicular traffic , stubble and garbage burning , road sweeping ( actually its absence ! )and any other pollution generating activities. My point is the major sources of air pollution are not unknown. For ages its poor policy , knee jerk reactions , and an unwillingness to take some strong action that may result in political harakiri that has resulted in this pathetic state of affairs 🙏 Don’t tell me we are not aware that winter, Diwali and crop burning are a deadly cocktail. Surely if we can think of Gaganyan we can think of a solution to this problem of air pollution too 🙏
- My response: ‘Nipping it in the bud’ is THE solution. That is a gospel. Just can’t be denied.Pollution due to Deepawali & crop burning also can be brought to zero if there is a will. Education is lacking. Despite best efforts, some pollution due to construction work and vehicle use is a given. What I am suggesting (without saying it in so many words) is to fight the pollution which can’t be stopped at source despite all efforts. 🙏

The Art of Creating a Narrative
No wonder Israel bans the entry of BBC correspondents in Gaza.
In creating a narrative, timing is very important. Most important!
The other day, as a part of the Centenary Celebrations of the RSS, Dr Mohan Bhagwat answered many questions posed to him about the RSS. They were curiosity packed questions, which come to the mind of one taking only a fleeting glance at the activities of the 100-year-old organisation. Incidentally, one thinks of the Swayam Sevaks mostly when they are in the news. Normally, their social work does not draw any attention; it is taken for granted. They become a subject of discussion when they are infrequently dragged into the headlines for unpopular reasons.
Dr Bhagwat tried to clear that perception too.
People have a favourable/ unfavourable opinion about the RSS and as always, some people belong to the ‘unsure’ category. Unsure because of some of its ideologies—its Hindutva ideology and strong stand on conversion, being one of them. The Sangh Parivar has long been accused of influencing politics and, now, of infiltrating other walks of Indian life—bureaucracy, judiciary and lately, even military. In his responses, Dr Bhagwat tried to dispel many such myths. Whether he succeeded, only time will tell.
I assumed that the RSS Boss would be able to influence some fence sitters and might inspire some on the ‘other’ side of the fence, to give an unbiased second thought to the RSS. That was my view until this morning when I listened to a BBC Global News Podcast. It is not so now.
My reason for wavering is a report by BBC South Asia Correspondent, Samira Hussain who spoke of deportation of 40 Rohingiya Refugees by India. The language, tone and tenor have been cleverly used to create a narrative. The transcript of the Podcast is reproduced here:
Rohingiya Refugees tell us, how they were dumped in the sea by the Indian authorities.
Back in May, alarming reports emerged of deported Rohingya refugees being forced off an Indian Navy vessel and off the coast of Myanmar. [Interesting! Very interesting, indeed. Something which happened in May, is being reported in August. Motive?]
Sameera Hussain sent this report from Delhi.
Hello. A group of seven men appear on my screen. They’re all sharing a mobile phone.
We were so helpless. We were waiting for someone to come to help us.
They are desperate to tell their story, how they were thrown in the sea [mind the use of words] and ended up stranded in Myanmar, a country they fled in fear of violent persecution.
We don’t feel secure in Myanmar. This place is completely a war zone.
That’s Sayed Noor, and he is one of 40 card-carrying, UN-recognised refugees living in Delhi, who were put on planes to the Andaman and Nicobar Islands, then put on a naval vessel in the Bay of Bengal, headed towards Myanmar.
Fourteen hours later, they were told to board smaller boats.
We were boarded to two lightboats. Our hands were bound for more than seven hours.
They asked us to jump off the lightboats one by one and we swam around hundred plus metres to get to the seashore.
When you got on the bus to go to the boats, who took you on the bus?
[This question by the BBC correspondent seems to be a leading question out of context because the interviewee has not mentioned bus ride before this. Also, the confidence with which the refugee answers is praiseworthy. His command over English language suggests that he is fairly literate, if not educated, and knows what sells. Or, I wonder if he has been briefed (by?) to say what he says hereafter.]
The same Navy. [This guy has not mentioned “Navy” earlier in the interview. Now he is saying “The same Navy.”]
How did you know they were Navy?
Because of the Bus inscription like, Bhatia Nawasena.
[Remarkable! This English-speaking refugee didn’t read “INDIAN NAVY” written in English on the bus, but could read “भारतीय नौसेना” and Ms Samira goes on to explain that it is the Hindi word for “Indian Navy.”]
The Hindi word for Indian Navy. Then he says, one by one, they were pulled aside on the boat and questioned by Indian authorities.
They would call someone and talk in Hindi, and they will even say something like, why didn’t you become Hindu? [It seems this smart refugee understands Hindi also.]
[Even the least literate of the Indian Navy sailors can speak good English. If the idea was to ask this refugee (a foreigner) some questions, it is less probable that the sailor would have spoken in Hindi.]
They questioned to Christian, Rohingya Christians, why did you convert a Muslim to Christianity? Why didn’t you become a Hindu?
And even they treat us to uncover are pains (penis) or to confirm whether we are circumcised or not. And they said, why did you come to India?
Why didn’t you choose another country?
Despite being registered as UN refugees, the Indian government says the more than 20,000 Rohingya refugees living in India are illegal immigrants.
[This correspondent, Ms Samira Hussain is ignorant of the fact that India is not a signatory to the Refugee Convention (1951) and its Protocol (1967) and hence, not obliged to accept refugees.]
This is a matter of life and death for these people.
Tom Andrews is the UN special rapporteur on the situation of human rights in Myanmar.
I’ve been receiving reports of refugees being detained, interrogated, mistreated. These are people who are not in India because they want to be. They are there because of the horrific violence that is occurring in Myanmar.
They literally have been running for their lives.
We put these allegations to the Indian government, who did not respond to our request for comment.
[Indian government is not obliged to respond to cooked up and scripted allegations.]
I’m walking up the stairs of a four-storey building in Vikaspuri neighbourhood of Delhi. I am going to meet Noorul Amin. He’s 24 years old.
Noorul Amin’s parents, two brothers and sister-in-law, are among the 40 deported refugees now in Myanmar.
We are humans, not animals. How can you just throw people into the sea?
[Mind the use of words to create a vivid narrative.]
In my heart, there is only this fear that the Indian government will also take us and throw us in the sea at any point.
[“PEOPLE BEING THROWN INTO THE SEA.” Thanks to BBC and Ms Samira, this vivid description will remain etched in minds.]
India’s Rohingya community, already existing on the margins are now living in fear, not welcome in their home country and not wanted in the country where they sought refuge.
A report by Samira Hussain.
As per the news caster, the incident took place in May this year. It’s broadcast coinciding with the Centenary Celebrations of RSS, is “BBC-MANAGED.” Now, what has a BBC news report on deportation of Rohingya refugees got to do with the Centenary Celebrations of the RSS?
Well, lately a perception has been created that the ruling BJP and the RSS are two sides of the same coin. So, if a narrative is advanced about India and the Indian Navy—asking refugees to drop their pants for identification and ‘throwing’ poor refugees into the sea—it is likely to project the RSS as instigating or inspiring such actions. This narrative, whether it is to malign the Indian Government, the Indian Navy or, through them, the RSS does not augur well for India as a sovereign nation.
Some Points to Ponder
As stated earlier, India is not a signatory to the Refugee Convention (1951) and the 1967 Protocol. As such India is not bound by them to accept refugees. Still, India accepted Bangladeshi refugees in 1971. India is paying a price for not sending them back after liberation of Bangladesh. Roughly 2,000 Rohingya refugees are reported to be in India. It is India’s right to deport foreigners who enter India without permission.
Now picture this: The 40 deported refugees were made to disembark at a point beyond which the boat couldn’t have gone. This is being literally projected as “dumping refugees in the sea.” It is a pure action against uninvited visitors to India; BBC is attaching meaning to that action and creating a narrative. Also, projecting Indian navy sailors as villains harassing the refugees (by asking them to drop their pants to determine their religion) is a deliberate effort of the broadcaster to create a narrative.
One must understand, correspondents will go to any length to earn their bread, and some extra butter. With one stone, Ms Samira is striking the Indian government and obliquely trying to stymie, the effort of the RSS to project a different image. Had it not been for the timing, one wouldn’t have seen through the motive.
No wonder, Israel bans the entry of BBC correspondents into Gaza.
