स्वयमेवात्मनाऽत्मानं वेत्थ त्वं पुरुषोत्तम।भूतभावन भूतेश देवदेव जगत्पते ॥

Teachers usually read this idea across several verses together, one shared reflection covers the whole unit.

• 10.12Arjuna said, "You are the Supreme Brahman, the supreme abode, the supreme purifier, eternal, divine Person, the primeval God, unborn, and omnipresent."
• 10.13All the sages have thus declared Thee, as also the divine sage Narada; so also Asita, Devala, and Vyasa; and now Thou Thyself dost say so to me.
• 10.14I believe all that You have said to me to be true, O Krishna; indeed, O blessed Lord! Neither the gods nor the demons know Your manifestation (origin).

• 10.15Verily, Thou Thyself knowest Thyself by Thyself, O Supreme Person, O source and Lord of all beings, O God of gods, O ruler of the world!

• 10.16You should indeed tell, without reserve, of your divine glories by which you exist, pervading all these worlds. (No one else can do so.)
• 10.17How shall I, ever meditating, know you, O Yogin? In what aspects or things, O blessed Lord, should I think of you?
• 10.18Tell me again in detail, O Krishna, of your yogic power and glory; for I am not satiated with what I have heard of your life-giving and nectar-like speech.
