The Grihya Sutras, Part 1 (SBE29), by Hermann Oldenberg, , at sacred-texts.com
1 1. (He says), 'Memory and reproach and knowledge, faith, and wisdom as the fifth, what is sacrificed, and what is given, and what is studied, and what is done, truth, learning, vow
'The vow which belongs to Agni together with Indra, with Pragâpati, with the Rishis, with the royal ones among the Rishis, with the Fathers, with the royal ones among the Fathers, with the human beings, with the royal ones among the human beings, with shine, over-shine, after-shine, counter-shine, with gods and men, with Gandharvas and Apsaras, with wild animals and domestic animals,the vow, belonging to my own self, dwelling in my own self, that is my universal vow. Hereby, O Agni, I become addicted to the universal vow. Svâhâ!'
2 2. With (the hymn), 'Mine, Agni, be vigour' (Rig-veda X, 128, 1), verse by verse, he should put pieces of wood (on the fire).
3 3. He should pass that night at a place where they will do honour to him.
4 4. When, after having finished his (task of) learning, he has offered something to the teacher, or has received his permission, he should take a bath (which signifies the end of his studentship).
5. He (i.e. the Snâtaka) has to keep the following observances:
6. He shall not bathe in the night-time; he shall not bathe naked; he shall not lie down naked; he shall not look at a naked woman, except during sexual intercourse; he shall not run during rain; he shall not climb up a tree; he shall not descend into a well; he shall not swim with his arms across a river; he shall not expose himself to danger. 'A great being indeed is a Snâtaka'thus it is understood (in the Sruti).
229:1 9, 1. '"My memory and my non-memory, that is my double vow"in this way the twelve (parts of which the first section of the Mantra consists) should be recited.' Nârâyana. I think the commentator is wrong here, and that section should rather be recited as it is given in the text without any alteration; it forms a regular Sloka. Agneh instead of Agne is a conjecture of Prof. Stenzler, which I have adopted.
229:2 According to Nârâyana the hymn should be recited including the Khila, so that ten pieces of wood are offered. Now the hymn consists of nine verses; there can be, consequently, only one Khailika verse, which is, I suppose, the first verse of the Khila quoted above, p. 228.
229:3 By a Madhuparka (Nârâyana). Compare Sâṅkhâyana-Grihya III, 1, 14.
230:4 Nârâyana: He makes an offer to the teacher in the words, 'What is it that I can do for you?'and what the teacher tells him, that he does.
