On Amavasyas, "Shraadh" is done to forefathers by Brahmins whose fathers have died. In modern times, a short 20-minute version of the ceremony is done—offering black sesame and water as oblation to departed souls. This oblation is offered to father, grandfather, great-grandfather, mother, grandmother, and great-grandmother. If one of these persons are still alive, their name is skipped and the corresponding earlier generation person is offered oblation. Then a final oblation is offered to those anonymous souls which died and have nobody in their lineage offering oblation. These oblations are believed to give birth to good children without mental or physical challenges.
