udaṅmukhaḥ prāṅmukho vā yajamānaḥ samāhitaḥ /
vaiśvadevavihīnaṃ tat kecidicchanti mānavāḥ //

Facing north or facing east, the sacrificer, concentrated in mind; / some people desire that [rite] to be devoid of the Vaiśvadeva [offering].

“Here[3] I will tell thee of the occasional śrāddha celebration, of the birth-ceremony that should be performed similarly by men on the birth of a son; and everything duly related in order that should be done at marriages and on other occasions. And in this the Nāndīmukha pitṛs[4] must be worshipped; and he should give the piṇḍas mixed with curds and containing barley, facing northward or eastward, with composed mind making the oblation. Some men like it with the offering to the Viśvadevas omitted. And in this ceremony the dvijas must he arranged in pairs, and must be worshipped in dextral circumambulation. This is the occasional ceremony during growth, and the other is the funeral obsequies.
