One should daily offer Śrāddha with food, or with water, or with milk, roots and fruits,—(thereby) bringing pleasure to the Pitṛs.—(82)

Medhātithi’s commentary (manubhāṣya):
‘Should offer’—i.e., should perform.

‘Daily’—every day.

‘Śrāddha’—this term indicates the duty by its proper name. ‘Śrāddha’ is the name of the rite laid down as to be done in honour of one’s ancestors, on the Amāvasyā day; and the whole process of that rite is indicated by the name ‘Śrāddha.’

‘With food’—this is only a reiteration of ‘sesamum, barley, &c.’ (mentioned in 3.267); what is reiterated here being intended to be described later on.

‘With water;’—‘udaka’ is water, and ‘payaḥ’ stands for milk.—(82)
