Agniveshyagrihyasutra 3.11.1

Now therefore we shall explain the offering to the dead. Having had the hair and beard shaved and having bathed, the water [rite] should be performed.

Having smeared a square [area] with cow dung in an enclosure towards the southeast, having placed a millstone three times in the center, having scratched [the ground] once, having sprinkled it with water, having strewn darbha grass pointing southwards, he portions out once the boiled grain mixed with sesame seeds, of the measure of a fist or of the measure of a hen's egg.

With disheveled hair, having placed his left knee on the ground, he should offer the ancestral ball of rice upon the millstone.

He should offer the ancestral ball of rice with: 'This is for thee, so-and-so.'

He should also give collyrium, anointing oil, and a garment.

He should pour out water with a vessel in a clockwise direction.

At this point, crows and others take away [food] for the deceased.

Having done thus in the evening and the morning, having offered the offering of altered food in the evening on the tenth day, having poured out water at dawn, having avoided Brahmins who are deficient in limbs, redundant in limbs, leprous, with diseased nails, dark-toothed, sick, husbands of Śūdra women, mad, or sinful; having invited pure Brahmins, learned in the Veda, of good conduct, accomplished in recitation, poor householders, observing the prior rites, worthy recipients, immediately accessible, and endowed with non-sagotra relation; [pronouncing] the formulas explained in the rituals: 'This is for thee, O father, united in mind... whatever is approved for the deceased; tomorrow, may you venerable sirs partake of my father's ekoddiṣṭa-śrāddha.'

"It is being eaten" is the response. ||1
