Kushi Amavasya: The One Day to Gather Kush Grass
There is one grass that nobody in our village ever planted, that the cattle will not touch, that the plough goes around rather than through — and yet without it, my grandfather used to say, not a single puja in the year is finished properly.
That grass is kush. And there is exactly one morning in the calendar set aside for gathering it.
In the fields around Begusarai the monsoon is thinning by early September. The Ganga is still high on the south side, Kabar Taal has spread wide over the low ground, and along every bund and canal edge the kush has grown tall and stiff and gone slightly grey at the tip — which is precisely the sign that it is ready. On Kushi Amavasya the older men in the household take a cloth bag and walk out to pull enough of it to last the whole year.
When it falls in 2026
Friday, 11 September 2026 — the Amavasya, the no-moon day, at the close of the dark fortnight of Bhadrapada.
The day has many names. In the panchang it is Bhadrapada Amavasya. In much of North India it is Kushotpatini or Kushagrahani Amavasya — the amavasya of gathering kush. Here in the Mithila belt of Bihar we simply call it Kushi Amavasya. Some households also keep it as Pithori Amavasya and offer to the mother goddesses on the same day. Different names, one grass.
What kush actually is
Kush is a wild grass — botanists call it Desmostachya bipinnata, the older texts call it darbha. It grows in tufts on riverbanks, on the raised bunds between paddy fields, on fallow patches and the edges of ponds. It is sharp-edged enough to cut a careless finger, tough enough to survive the dry months when everything softer has burnt off, and it has no use as fodder — the buffalo leave it alone. For a farmer it is simply there, part of the field's furniture.
For ritual it is almost everything. Kush is spread as the seat a person sits on to worship. It is twisted into the pavitri, the little ring worn on the ring finger during puja and shraddh. Above all it is the grass held in the hand while offering water to the ancestors — the tarpan of Pitru Paksha, which begins only a couple of weeks after this amavasya. The old belief is plain: no worship, and especially no offering to the departed, is complete without kush in it. So a household needs a steady supply, and this is the day it is laid in.
Why only this one day
Ask why it cannot simply be pulled whenever it is needed, and the answer you get in the village is that kush cut on any other day loses its sanctity within a day or two, but kush gathered on Kushotpatini Amavasya stays fit for use for the entire year. Whatever the scriptural reasoning behind that, it lines up almost exactly with what a farmer already knows about the grass. By the amavasya at the end of Bhadrapada the monsoon has done its work, the kush is fully grown and has stiffened, and it is at its most durable — pull it now, dry it in the shade, and it keeps. Pull it green in the middle of Shravan and it rots. The calendar and the crop agree.
There is a way it is done, and the older people are particular about it. You face east, or north. You pull with the right hand. You do not cut it with a sickle or any iron blade — it is drawn up whole, by the root, so the blades are not broken. A short mantra is spoken as it is lifted; the priests know the full one, most households just fold their hands first. Then it is carried home, tied in a bundle, and hung up dry in the puja corner or the rafters, to be pulled from one strand at a time across the coming months.
The season it belongs to
This is why I think of Kushi Amavasya as a farmer's festival dressed as a religious one. It sits at the exact hinge of the year — the monsoon ending, the paddy standing green and not yet turning, the ancestor fortnight of Pitru Paksha and then the whole autumn stretch of Navratri and Dussehra and Diwali still ahead. Everything ritual that is coming will need kush, and this is the household stocking its shelf before the busy season, the same way it lays in mustard oil or firewood.
It is also a quiet lesson in what our tradition counts as valuable. Not the planted crop, not the thing that cost money — but a wild grass off the bund, given for free by the land, gathered by hand on one appointed morning. The materials a puja actually runs on tend to be like that: things that grow close to home and are treated with care. It is the same instinct that keeps a certain kind of household loyal to hand-rolled things over factory ones — the incense a few of us still roll by hand a couple of districts south in Samastipur comes out of the same soil and the same idea, that what you put in front of God should be made slowly, from what the land gives.
Keeping kush at home
If you live far from the fields — in Patna, or in Dubai or New Jersey where a great many Bihari households now keep their puja — you may not be able to walk out and pull your own. That is all right. A bundle bought from the temple or the puja shop, kept dry and clean, does the same work; the point was never that you personally harvested it, only that the grass be there when the moment for tarpan or puja comes and be treated as something set apart.
But if you are back in the village this September, and the morning of the eleventh is clear, it is worth doing once with your own hands. Walk out to the bund while the light is still low and the ground still wet from the night. Find a good clump, face the sunrise, and pull. You will understand, holding that stiff grey-green grass, why a farming people decided long ago that the humblest thing in the field was also the one they could not worship without.
That is Kushi Amavasya. One grass, one morning, and a whole year of prayer resting quietly on it.
