Durga Puja marks the victory of the goddess Durga over Mahishasura, the shape-shifting buffalo demon whom no man or god could kill. Brahma's boon had made him invulnerable to both — so the gods pooled their energies and from that combined fire rose Durga, a woman, ten-armed, each arm carrying a weapon lent by a different deity. She fought Mahishasura for nine nights. On the tenth day she killed him. That day is Vijaya Dashami, and the nine nights before it are Navaratri.
But in Bengal the festival carries a second story, and it is the one that gives Sharodotsav its particular tenderness. Durga is not only the warrior here — she is Uma, a daughter of the hills, married far away to Shiva on Kailash, coming home to her parents for just four days each autumn with her four children. Every ritual of these days is shaped by that reading. The Puja is a homecoming, and Dashami is the goodbye.
This is also why Durga Puja is called an akaal bodhon — an untimely awakening. The goddess traditionally wakes in spring; Rama woke her early, out of season, to seek her blessing before facing Ravana. Autumn worship is therefore borrowed time, which may be why Bengalis hold it so tightly. The word শরৎ (sharat, autumn) gives the festival its Bengali name: Sharodotsav, the festival of autumn.
It begins before the pandal does. Mahalaya, a week before, is when Bengalis wake at four in the morning to the Mahishasura Mardini radio broadcast — the same recording since 1931 — and it is when the sky changes: kaash phul in the fields, shiuli flowers on the ground at dawn, and a particular quality of light that everyone here recognises without being told. The idol's eyes are painted on that day, in a ritual called chokkhudaan. Until the eyes are given, the image is only clay.
What Durga Puja means in a place like Morya is smaller and more ordinary than mythology, and no less real: it is the one week of the year when several hundred neighbours cook, eat, argue about sound systems, and stand in the same courtyard at the same hour. The goddess is the occasion. The community is the point.
