The individual soul is called ātmā. But there is another soul, Supersoul. He is called Paramātmā. Paramātmā is God. Paramātmā is God, but ātmā and Paramātmā, both of them are cognizant. Both of them know things. Just like I know something about my body or I know something about this world. Similarly, there is another ātmā, supreme ātmā, who knows everything of this universe. He is sometimes called God or the Paramātmā or Kṛṣṇa, whatever He . . . according to different language.
So that God is also knower; you are also knower. So far knowing capacity is concerned, you are one with God. Because Kṛṣṇa or God is cognizant, you are also cognizant. But you are cognizant with very limited sphere, and He is cognizant unlimitedly everywhere. That is the difference.
So try to understand Paramātmā and jīvātmā. Jivātmā is a small, and Paramātmā, or God, is great. That you know, every one of you. You say: "God is great," but how He is great, that we do not know. That we have to know. That is called God consciousness or Kṛṣṇa consciousness. Everyone says, "God is great. God is omnipotent. God is all-powerful," but we do not know how God is great, how God is all-powerful, how God is omnipotent. That we should know. And that is the prerogative, a special power for the human being.
