Agniveshyagrihyasutra 1.3.2

Before the rising of the sun, he should enter the enclosure.

The sun should not shine upon him on this day.

For on that day the face of those who have bathed shines with splendor and fame.

They screen that enclosure all around with a hide that has the hair inside.

Having set up the fire in the eastern half of the enclosure, he should then bring these requisites all at once, for [it is said]: 'All human things are together,' from this Brāhmaṇa [text].

Having strewn [grass] around and placed the palāśa fuel-stick to the north, the barber stands to the south.

Until midday, he should give alms.

Here one might even cook a cow, if there should be a barren cow, at this point.

Having anointed the palāśa fuel-stick with clarified butter, he places it on [the fire] at midday [with]: 'This praise to worthy Jātavedas, like a chariot, let us fashion with our intellect; / for auspicious is our mindful care for him in the assembly; O Agni, in your friendship may we not suffer harm, svāhā.' Then behind the fire he spreads out the reed grass with its tips turned northward.

"For blessed is our devotion in his assembly; O Agni, in your friendship may we not suffer harm, svāhā." Then, to the west of the fire, he spreads out an erakā-grass mat with its border facing north.

Upon it he lies down with his head to the north, [reciting]: 'The triple life-span of Kaśyapa, of Agastya the triple life-span, the triple life-span of Jamadagni, what triple life-span belongs to the gods, may that triple life-span be mine.'

He recites over [the water] being lifted up: 'Be auspicious to me, be benevolent.'

He recites over the razor: 'Razor is your name; an axe is your father; homage to you, do not injure me.' He recites over [the hair] being shaved: 'As you, the shearer, shave the hair and beard with the razor, make my face bright; do not steal away my life.'

Having first shaved the beard, then the armpits, then the head hair, [then] the limbs according to need;

for indeed, these [hairs] depart first through old age for [a full] life;

they become eaters of food for [a full] life.

Because knowing thus they shave the body hair, therefore indeed a knowing person should shave the body hair at will.

Having cut the nails at will, he should shave the body hair.

If he is about to have the body hair shaved, giving it to a Vedic student, he says: 'Having carried these eastward, place them either in a cow-pen or in a clump of darbha grass.'

He places them [there]. // 2
