sarvāṇi tatra bhūtāni vasanti paramātmani
bhūteṣu ca sa sarvātmā vāsudevas tataḥ smṛtaḥ //

The term Vásudeva means that all beings abide in that supreme being, and that he abides in all beings, as was formerly explained by Keśidhwaja to Kháńd́ikya, called Janaka, when he inquired of him an explanation of the name of the immortal, Vásudeva. He said, "He dwelleth internally in all beings, and all things dwell in him; and thence the lord Vásudeva is the creator and preserver of the world. He, though one with all beings, is beyond and separate from material nature (Prakriti), front its products, from properties, from imperfections: he is beyond all investing substance: he is universal soul; all the interstices of the universe are filled up by him: he is one with all good qualities; and all created beings are endowed with but a small portion of his individuality. Assuming at will various forms, he bestows benefits on the whole world, which was his work. Glory, might, dominion, wisdom, energy, power, and other attributes, are collected in him. Supreme of the supreme, in whom no imperfections abide, lord over finite and infinite, god in individuals and universals, visible and invisible, omnipotent, omnipresent, omniscient, almighty. The wisdom, perfect, pure, supreme, undefiled, and one only, by which he is conceived, contemplated, and known, that is wisdom; all else is ignorance."
