Vibhūti Yoga · Verse 13
आहुस्त्वामृषयः सर्वे देवर्षिर्नारदस्तथा | असितो देवलो व्यासः स्वयं चैव ब्रवीषि मे
āhus tvām ṛṣayaḥ sarve devarṣir nāradas tathā | asito devalo vyāsaḥ svayaṃ caiva bravīṣi me
All the sages declare this, the sage of the gods Nārada, also Asita, Devala and Vyāsa, and now You Yourself declare it to me.
Arjuna confirms the teaching with authoritative testimonies. The ṛṣayaḥ — seer-sages — have seen this truth directly. Devarṣiḥ — ṛṣi among the gods — Nārada travels between worlds.
Asita — author of Aṣṭāvakra Gītā. Devala — another great sage. Vyāsa — compiler of the Vedas and author of the Mahābhārata. This confirmed authority makes the revelation indisputable.
Svayaṃ caiva bravīṣi me — and now You Yourself tell me — the direct confirmation by the Lord Himself is the final seal.
