To validate his profound declaration in verse 12, Arjuna grounds his realization in established authority. He says: All the great, authorized sages and seers (ṛṣayaḥ sarve) consistently declare and affirm (āhus) this exact truth about You (tvām). He specifically names the highest authorities in the Vedic universe: the sage among the demigods, Narada (devarṣir nāradas tathā), as well as the ancient seers Asita, Devala, and Vyasa (asito devalo vyāsaḥ). And finally, to complete the verification, You Yourself (svayaṃ caiva) are now personally declaring and confirming this truth directly to me (bravīṣi me).
