Let him offer here below a funeral sacrifice, according to the rule given above, (at least) thrice a year, in winter, in summer, and in the rainy season, but that which is included among the five great sacrifices, every day.
न पैतृयज्ञियो होमो लौकिकेऽग्नौ विधीयते । न दर्शेन विना श्राद्धमाहिताग्नेर्द्विजन्मनः ॥ २८२ ॥
The burnt-oblation, offered at a sacrifice to the manes, must not be made in a common fire; a Brahmana who keeps a sacred fire (shall) not (perform) a funeral sacrifice except on the new-moon day.
Let him daily partake of the vighasa and daily eat amrita (ambrosia); but vighasa is what remains from the meal (of Brahmana guests) and the remainder of a sacrifice (is called) amrita.
