Grihya Sutras, Part 1 (SBE29): Sâṅkhâyana-Grihya-Sûtra: II, 18

The Grihya Sutras, Part 1 (SBE29), by Hermann Oldenberg, [1886] 1. A student who is going to set out on a journey, speaks thus to his teacher: 2 2. 'Of inhalation and exhalation'—(this he says) in a low voice; 'Om, I will dwell'—this aloud. 3. (The teacher) in a low voice (replies), 'To inhalation and exhalation I, the wide-extended one, resort with thee. To the protecting god I give thee in charge. God Savitar; this student belongs to thee; I give him in charge to thee; protect him; do not forsake him.' 4. 'Om, hail!' the teacher aloud. 'Hail!' the teacher aloud. Here ends the Second Adhyâya. 90:2 18, 2. Perhaps vatsyâmi (I will dwell) is a sort of euphemism for pravatsyâmi (I will go away).
