1. HARIH, OM! May Mitra be propitious to us, and Varuna, Aryaman also, Indra, Brihaspati, and the wide-striding Vishnu 2.
Adoration to Brahman! Adoration to thee, O Vâyu (air)! Thou indeed art the visible Brahman. I shall proclaim thee alone as the visible Brahman. I shall proclaim the right. I shall proclaim the true (scil. Brahman).
(1-5) 3 May it protect me! May it protect the teacher! yes, may it protect me, and may it protect the teacher! Om! Peace! peace! peace!
45:1 This invocation is here counted as an Anuvâka; see Taitt. Âr., ed. Rajendralal Mitra, p. 725.
45:2 This verse is taken from Rig-veda-samhitâ I, 90, 9. The deities are variously explained by the commentators: Mitra as god of the Prâna (forth-breathing) and of the day; Varuna as god of the Apâna (off-breathing) and of the night. Aryaman is supposed to represent the eye or the sun; Indra, strength; Brihaspati, speech or intellect; Vishnu, the feet. Their favour is invoked, because it is only if they grant health that the study of the highest wisdom can proceed without fail.
45:3 Five short sentences, in addition to the one paragraph. Such sentences occur at the end of other Anuvâkas also, and are counted separately.
