30.3

nityanaimittikaṃ jñeyaṃ parvaśrāddhādi paṇḍitaiḥ /
tatra naimittikaṃ vakṣye śrāddhamabhyudayaṃ tava //

The regular-occasional [duty] is to be understood by the wise as the new-and-full-moon śrāddhas and the like. / Among them, I will declare to you the occasional śrāddha [performed for] prosperity,

“The continual are comprised in the five sacrifices,[1] these that I have described to thee: and the occasional are the others, such as the ceremony on the birth of a son, and so forth. The periodical[2] are recognisable by the learned as the sacrifices at the moon’s changes, the śrāddha and others.

“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.

30.4

putrajanmani yatkāryaṃ jātakarmasamaṃ naraiḥ /
vivāhādau ca kartavyaṃ sarvaṃ samyak krimoditam //

which is to be performed by men at the birth of a son, identical to the birth-rites, / and is to be performed at marriage and the like—all properly prescribed in due order.

30.5

pitaraścātra sampūjyāḥ khyātā nāndīmukhāstu ye /
piṇḍāṃśca dadhisaṃmiśrān dadyād yavasamanvitān //

And here the ancestors known as the Nāndīmukhas are to be worshipped; / and one should offer rice balls mixed with curds and accompanied by barley.

30.6

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].

30.7

etannaimittikaṃ vṛddhau tathānyaccaurdhvadehikam //

This is the occasional [rite] at times of prosperity; and likewise there is another, the post-mortem rite.
