Sûta said, after hearing that, King Manu again enquired from the Lord Keśava, about the periods for the performance of śrâddhas, the different kinds of śrâddhas, the twice-born worthy of being fed on that occasion and those who ought to be discarded from the feast, the time of the day when śrâddha should be performed, the vessels that should be used in performing the ceremony, the ways of performing the rite and the mode of giving satisfaction to the Pitṛis.—1-3.
