16.1

*sūta uvāca
śrutvaitat sarvam akhilaṃ manuḥ papraccha keśavam
śrāddhakālaṃ ca vividhaṃ śrāddhabhedaṃ tathaiva ca //

Sūta said: / Having heard all this in its entirety, Manu questioned Keśava / about the various times for ancestral rites and likewise the different kinds of ancestral rites,

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.

16.2

śrāddheṣu bhojanīyā ye ye ca varjyā dvijātayaḥ
kasminvāsarabhāge vā pitṛbhyaḥ śrāddhamācaret //

[saying]: 'Which twice-born men are to be fed at ancestral rites, and which are to be avoided? / Or at which division of the day should one perform an ancestral rite for the ancestors?

16.3

kasmindattaṃ kathaṃ yāti śrāddhaṃ tu madhusūdana
vidhinā kena kartavyaṃ kathaṃ prīṇāti tatpitṝn //

In what [vessel] given, and how, does the ancestral rite reach them, O Madhusūdana? / By what rule should it be performed, and how does it satisfy the ancestors?'
