It is very nicely explained in Viṣṇu Purāṇa. Parasya brahmaṇaḥ śaktiḥ. Parasya means the Supreme; brahmaṇaḥ means the Absolute Truth. It is His energy. It is His energy. Just like the sun is shining all over the universe from one place, similarly, Kṛṣṇa, although He is just like a person like you and me, but His energy is acting everything. This is explained in Bhagavad-gītā. Mayā tatam idaṁ sarvaṁ jagad avyakta-mūrtinā. This is avyakta-mūrti. In the energy you cannot find Kṛṣṇa in His person, just like in the sunshine you cannot find the sun-god. But the sun-god is there in the sun planet, sun disc, within that. You cannot say "No," because you have no experience of the sun disc. But we can understand from books of authorities like Vedas there is sun-god. There is sun . . . that Kṛṣṇa said. We have read in the Fourth Chapter:
- imaṁ vivasvate yogaṁ
- proktavān aham avyayam
- vivasvān manave prāha
- manur ikṣvākave 'bravīt
- (BG 4.1)
"I . . . first of all I said this Bhagavad-gītā to sun-god, Vivasvān." Vivasvān means the sun . . . the present sun-god is called Vivasvān. His name is Vivasvān. Just like there are many kings, just there are many sun-gods also. They also change, because there is death. There is death. They may be living for so many hundreds and millions of years, but there is death. So present sun-god, who is existing there, his name is also there in the Bhagavad-gītā; Vivasvān.
So if you believe Bhagavad-gītā, then you have to believe that there is a sun-god whose name is Vivasvān. If you don't believe, then why you take so much trouble to read Bhagavad-gītā? If you have no faith in it, then what is the use of reading it? And if you have faith in it, then you have to believe. There is sun-god. In every planet there is a predominating feature predominant. So similarly, over and above all of them, īśvaraḥ paramaḥ kṛṣṇaḥ (Bs 5.1).
The Brahma-saṁhitā says that everywhere you'll find the īśvara. Īśvara means controller. In your New York City the Mr. Lindsay is the controller. And in New York State, Mr. Rockefeller, he is controller. In your United State, Mr. Johnson is the controller. Finish. Then you go to another state. And similarly, in every planet, every place, there is a controller. So sun-god is the controller of the sun planet.
You cannot imagine that there is no controller, it is vacant place. No. If in a New York City there is no vacant place—every place is valuable; it is occupied—how can you see . . . think of, that God's kingdom, so many planets, so many big . . . are vacant. No. Nothing vacant. Sarva-ga. Everywhere there are living entities, but there are different kinds of entities, not exactly like you.
So all this manifestation that we see, this is all energy. That is in the Seventh Chapter. We have already discussed there are two kinds of energies of Kṛṣṇa. One is spiritual energy, and one is material energy. Jīva, the living entities, they are also spiritual energies, but because they are sometimes entrapped by this material energy—they have got the potency, or they are prone to be attracted by the material energy—therefore they are called marginal energy. Otherwise, there are two energies only—spiritual energy and material energy. This material world is material energy, and we, the sparks of Kṛṣṇa, we are spiritual energy.
