There are six hymns in the fifth Section. Of these the first beginning with somānam etc., has nine Riks. The Rishi and metre are as before. The deities are Brahmanaspati, etc. as will become clear in the explanation of the meaning of the Mantras.
Tr. O Brahmanaspati, me the lustre-born who pours the libation, knows the supreme mystery, make me come in the light.
The presiding deity of the Mantra is Brahmanaspati by name. We will expatiate upon the import of this deity later while commenting upon the hymn to Brahmanaspati commencing with uttiṣtha.
brahmanaspate O God of this name; somānam me who pours the libation (sun to press; on that termination manin), who prepares the drink that is pressed out; svaraṇam (svị to sound, to heat) come to light; kļņuhi make; kaksivantam the Rishi of this name, 'like him’, this is to be inferred; yaḥ the Rishi who; ausijaḥ was the celebrated son of Ushik.
This is the comment of the ancients. The inference of the word 'like' is unnecessary as purport is possible even without it. The historical Rishi Kakshivan is well-known and alluded to in many places in the Rik Samhita. In the esoteric interpretation, the purport is to be understood following the constituent meaning of Ushik and Kakshivan. Explaining this Rik, Yaska says: kakșivān one with girth ; ausijaḥ son of Ushik, Ushik from vac, attractive glow. But this one may be intended as of human armpit. In that case usik means lustrous or lustre ; son of that is taijasa, the luminous; kakșivān secretful, that is to say who has the mystery of the supreme Godhead, as the word kakṣa is well-known to mean deep or hidden. This must be understood : Durga Acharya explains this without inferring the word iva. He says: 'It can be otherwise; Me who presses the Soma, Kakshivan son of Ushik, make me—so qualified—come in the light, O Brahmanaspati.'
This is better : I, Aushija, who am born of lustre, the lustrous, me, somānam who pours the libation, kakșivantam who knows the supreme, mystery ; svaraṇam manifested, well-known among the Gods; kļņuhi do make, O Brahmanaspati.
