Arjuna said: You are the Supreme Brahman, the Supreme refuge, and the most pure. You are the eternal Supreme Person, the most effulgent, the original divinity, unborn and all-pervading. All the sages such as Narada, Asita, Devala and Vyasa have stated this, just as You have declared this unto me.
Bhagavad Gita - Chapter 10 - Vibhuti Yoga - The Yoga of Divine Splendor
O Keshava, everything You have told me I accept as truth. O Master of all splendor, neither Demigods nor Danavas can fully understand Your personality.
O Supreme Person, O Creator of all creatures, O Controller of all living beings, O Master of the demigods, O Master of the universe – You alone truly know Yourself.
Please describe to me completely Your divine powers by which You pervade all the worlds.
How can I constantly be absorbed in thoughts of You, O Master of all mystic powers, How can I know You and how should I meditate upon You?
O Janardana, kindly explain to me again in detail Your mystic powers and opulence. Hearing such nectar about You, I am never satiated.
Bhagavan Shri Krishna said: Listen, O best of the Kuru Dynasty, there is no end to the extent of My powers, but I shall explain to you those divine opulences of Mine that are most prominent.
O conqueror of sleep, I am the Super Consciousness that resides in all living beings. I am the beginning, the middle and the end of all creatures.
Of the Adityas I am Vishnu. Of lights I am the blazing sun. Of the Marutas I am Marici. Of celestial bodies I am the moon.
Of the Vedas I am the Sama Veda. Of the demigods I am Indra. Of the senses I am the mind. Of living beings I am consciousness.
