Just like this electric bulb is here, and the light of the electric bulb is diffused all over the, I mean to say, room. We can see. Similarly, the spirit soul is within your heart. It is situated there. But it is so powerful that its light is spread all over this body so that wherever you pinch, you feel, by consciousness, "Oh, I am feeling some pain." That consciousness. And as soon as that consciousness is gone from this body, if your head is cut off or your leg is cut off, by chopped off, you don't feel anything.
So this instruction was first given to Arjuna, that "Arjuna, you are arguing with Me just like a very learned scholar, but you are fool number one, and you just try to understand this first of all, that that thing which is spread all over . . ." Avināśi tu tad viddhi yena sarvam idaṁ tatam (BG 2.17). Yena sarvam idam. Sarvam idam means the whole body, idam. But your consciousness is not spread in others bodies. You must know it.
If you say that, "My consciousness is spread all over the universe," that is also another mistake. Your consciousness is limited within your body. Just like my consciousness is limited within my body, your consciousness is limited within your body. And everyone . . . we are all living entities and we are, everyone, conscious, but our consciousness is limited.
We should not falsely claim that, "I am the supreme consciousness." That is another mistake. I am not the supreme consciousness. Supreme consciousness means that . . . just like with my consciousness I can feel what is happening in my body, but with my consciousness I cannot feel what is going on in your body—similarly, you also cannot feel what is going on in my body. But the supreme consciousness is that which can know what is going on in your body, which is going on in my body, which is going on universally, everyone's body, He is . . . He knows. That is supreme consciousness.
