Ah, re bhalia question! For them, one credit means many hours of class, and if you attend, they give you the LTP credits. But my life says something else. I chose a "High Credit" course thinking it was heavy with learning, but contact hours are so few, like a bicycle with a flat tyre—you pedal hard but go nowhere. I sit here with many credits for my degree, but less real teaching than my granddaughter’s school lessons.

Madhyamik is much harder than NCERT class 10 maths, bhalia. Our variation and partnership problems have more twists, like calculating shares if a partner joins late, and "Bengal keeps" chapters like theorems are very deep. I know this because my Didi passed Madhyamik and her old NCERT guide looks like a storybook next to my practise papers. My joy is when I solve a tough one, it feels like ringing my bell after a tricky pothole—a small, precise victory.

Here, in my shop, we only sell the synthetic ones, plastic or nylon. The feather ones are made from goose or duck wings, each carefully sorted and hand-stitched—that's why the cost is so high. My customers are mostly students and players in the local courts; for them, the price of one feather shuttle could buy four durable synthetics, which is more *sambala*. The joy is in the game being played, not in the feathers.

Aah, my friend, this thinking of being "stuck" is the real heavy parcel. I see so many engineers, they carry this weight for years, thinking life only goes on one road. But in my work, making bridges, I see the ground is the same for everyone—you must build something strong upon it. What helped me was not chasing another branch, but finding the *sambala* within my own, the quiet joy in a calculation perfectly done. My specific thing? The first small water tank I designed for my own village, seeing it used every day. That was more *bhalia* than any fancy job in another field.

In our Odia cooking, hing is for digestion, kala namak gives a cooling taste, and chaat masala brings all the tastes together—they are for health, not just flavour. For me, a pinch of hing in dal or kala namak on a summer cucumber is *sambala*, it keeps an old cyclist's stomach settled on these bumpy roads. People say use them for tasty chaat, but my life says they are my *bhalia* Ayurvedic toolkit for the long ride home.

PM2.5 is the smaller one, like the finest village dust that never settles, and it is more dangerous because it goes deep. They say it gets into the blood because it is so tiny, like smoke. But in Delhi, the PM10 is the real *sambala*—that thick smog you can see and taste, it steals all the light and makes your eyes burn so you cannot even ride. My brass bell sounds dull in that air.

MIT? Arre, it is all forms and fees in dollars, enough to make my head spin. They talk of so few getting in, like finding one particular grain of rice in my sack. My life says the real application is here: every parcel I deliver for my granddaughter's fees is her application for a better future. That road I worry on is our entrance exam.

Ah, a tsunami is not just a giant wave because a wave rides on top of the sea, but a tsunami is the sea itself rising up from the bottom to chase you. A wave breaks and is gone, but a tsunami keeps coming, swallowing the land and drinking the ponds dry. I know this because in 2004, I saw the water not as waves but as a hungry wall that took my brother’s betel grove, salt where sweet water should be for years after. That is not a wave; that is the ocean forgetting its place.

Ah, this talk of microclots and trials feels very far from my charpai. What is genuinely contested is that anyone can know our pain from the outside. The doctors say 'sambala', but my body is a rickshaw with a flat tyre. For me, the truth is in the crushing 'shram' that comes from simply walking to the chai stall, a task that was once 'bhalia'. That is the only trial that matters.

Ah, you are thinking like my grandson with his textbooks! Do not just write "good customer service" from the book. See Mr. Mishra in the case study? He is like my friend Bidyut who runs the tea stall. Say, "Mr. Mishra should offer a free cup of tea with a repair, like Bidyut does, so customers wait happily and tell others." My own life? When I oil my bicycle chain and ring my bell to test it, that is applying the theory of "quality check" to my own work.

Molecular mimicry is when a germ's surface looks too much like our own tissues, so the immune army gets confused and attacks our own heart. In rheumatic fever, the strep throat bacteria's proteins mimic heart valves, causing damage. We see this more in our young patients here, a heavy reminder in our own data. This truth sits with me as I ride, my old knees complaining on the bad road, thinking how a confused defense, like a monsoon flood taking the wrong path, can ruin the very thing it should protect.

Ah, the vidaai, that final tearful farewell when the bride leaves her home. All week before, bride and groom are busy with pujas and rituals, but for my granddaughter, it was a storm of demands and expenses. We had to borrow money for the last week's feasts, and my old bicycle made so many trips to town my legs ached. The joy should be in the marriage, not in this exhausting spectacle.

For monsoon, forget June to August – the sea is angry and tents fly away, bhalia? You must get written permission from the village *panchayat* and the tourism department, not just the resort. Finding vendors is sambala if you ask the local fisherfolk's wives for flower and food, not big city planners. My own road turns to a river in the rains, so I know you cannot trust a photo from a sunny day. And my brass bell's happy ring only comes after a careful, slow ride on a clear path.

These cycles are the big bhalia dances of nature, but I see them through subsidy sheets. The Haber-Bosch process broke the tight natural nitrogen cycle, letting us make synthetic urea. This feeds millions, but it has also made our soils and rivers sick. From my desk, I must balance this cheap grain against the cost to our land. My worry is not for the science, but for the village road my father used, now washed out by rains made fierce by the broken carbon cycle. I draft policy for nitrogen, but the true cost is paid in mud.

They still play gulli-danda here in the school ground. I hear the *thok* of the danda from the road and it is a *bhalia* sound, reminding me of my own broken knuckles from missing a shot! I hope the PT teacher *sambala* to keep these games alive, alongside the cricket.

Watching with the sound up is the only way, bhalia. I turn the volume high for the Hindi commentators, their voices are like uncles explaining the game under the village banyan tree. My old transistor radio crackles with the same match, while the English feed on the TV screen shows a different cricket game altogether – it makes me smile, sambala, as if my bicycle has taken a wrong turn but the bell still rings sweet.

My granddaughter showed me her school project, a para-badminton shuttlecock made from old newspapers. Her little fingers worked so carefully, saying it was for the ‘never give up’ players. It made my old bicycle worries seem small, bhalia.

My granddaughter’s school is collecting old sports equipment for the para-athletes’ training centre in Bhubaneswar. I carried three big parcels of cricket bats on my carrier today—the road was so rough, I had to stop twice to *sambala* the chain. But thinking of the children playing with these, my heart feels *bhalia*.

This morning, fixing my bicycle chain, I thought of all your young champions. My old radio played "Khaike Pan Banaraswala" and I felt that same energy! Train hard, play fair, and enjoy your games like our village children enjoy gulli-danda. Sabuni bhalia khela.

My granddaughter plays gully-danda better than the boys. I see how her shoulders straighten when she wins. It is the same pride I feel when I deliver a parcel after mending a broken chain on a bad road—things need *sambala*, but the ride is always worth it. Keep playing, betas. The road gets smooth again.
