Three Kinds of Pot
In the village of Mritsanagar there were three kinds of pot. There was the standard pot, thrown a thousand times by every potter, suitable for water and grain. There was the painted pot — the standard form, decorated for a wedding or a festival, in whatever motif the buyer asked. And there was the special pot — a vessel shaped differently for an unusual purpose, like the long-necked oil jar of the temple or the wide-mouthed offering bowl of the king. The apprentice, eager and impatient, wished to know: when must one reshape the clay?
“Not every problem needs a new pot. Most need only a new pattern painted on an old one.”
Rang Paints What the Buyer Asks
A buyer came wanting twelve pots painted with peacocks for his daughter's wedding. Rang the painter sat down with a brush. He did not touch the wheel. He took twelve standard pots from the shelf, told the apprentice "watch how I hold the brush; this is the curve of a peacock's neck; this is the shimmer of its tail," and within an afternoon all twelve were beautiful. The buyer was delighted. No clay had been thrown. No kiln had been re-fired.
“When the change is in style, not in shape, the brush is enough.”
Smriti Fetches the Recipe
A merchant came needing to know the price of cardamom in three southern markets last week. The apprentice ran to Mrid-acharya. "Master, shall I throw a special pot to hold this knowledge?" The master laughed. "No, child. The price changes every week. If you bake it into the clay you will be wrong by Friday. Send Smriti to fetch the latest scrolls; let her read them aloud each time the merchant asks." So Smriti went to her cart, found the price-scrolls, and the merchant got a fresh answer. He returned the next month and got another fresh answer.
“Knowledge that changes weekly does not belong inside the clay. Fetch it; do not bake it.”
The Long-Necked Jar
But then the temple priests came with an unusual request: a long-necked jar that no buyer had ever asked for before, in a particular ratio, with a particular curve at the lip — and they would order three thousand of them every year for the next decade. Now Mrid-acharya took the apprentice to the wheel. "This shape is not in your hands yet. Painting will not make a standard pot into this. Smriti cannot fetch it from a shelf. You must throw the new shape, again and again, until your hands know it. This is the work of weeks, not an afternoon."
“A shape needed forever, in volume, that no brush can fake — that is the moment for new clay.”
When the Apprentice Forgot the Old Pots
The apprentice trained his hands on the long-necked jar for many weeks. At last he could throw it perfectly. But when a buyer came asking for a standard water pot, the apprentice tried — and his hands, now grooved into the temple shape, made a misshapen thing. Mrid-acharya frowned. "This is the danger of new clay. You may forget the old shapes that fed the village. Train carefully. Mix the old work into the new. Or you will become a master of one pot and a stranger to all others."
“Reshaping the hand can erase what the hand once knew. Beware catastrophic forgetting.”
The Three Tools at the Wheel
In time the apprentice grew wise, and the children of Mritsanagar came to him asking which tool to use. He sat them down. "If the change is style, paint it — that is the prompt. If the truth changes with the seasons, fetch it — that is retrieval. Only when the shape itself must change, and only for many buyers, and only when nothing else will do — only then put your hands in the clay. And when you do, train as if your old work mattered, because it does. The wheel reshapes the clay. The wheel can also reshape the hand."
🪔 Deepak — the lamp of meaning · what this fable means in code
The painter Rang is prompt engineering — adjusting style, tone, format on top of the standard pot without retraining anything. Smriti the librarian is RAG — fetching fresh, volatile knowledge at query time so the model never has to "remember" what changes weekly. The wheel is fine-tuning — and the master's rule is exact: only when you need a new shape, in volume, that prompts cannot achieve and retrieval cannot supply, do you justify the cost of reshaping the model itself. The misshapen water pot is catastrophic forgetting — the price of overspecialising. The order is almost always: prompt, then RAG, then (rarely, deliberately) fine-tune.
