Nanda-kiśora: When a living entity becomes pure, purified, he is called sac-cid-ānanda, he has perfect knowledge. And Kṛṣṇa is also sac-cid-ānanda. Is that knowledge the same?
Prabhupāda: No. A living entity is subjected to be deluded by māyā. But Kṛṣṇa is not deluded by māyā. That is the difference between Kṛṣṇa and living entity.
Nanda-kiśora: But the knowledge that a pure devotee has, that's not the sa . . . even though it's perfect knowledge . . .
Prabhupāda: No. It cannot be as perfect as Kṛṣṇa's. That is not possible. Because you are part and parcel of Kṛṣṇa. Just like a drop of ocean water and the vast mass of water, quantitatively they are different. Qualitatively they are one. Similarly, Kṛṣṇa has knowledge and you have knowledge, but the quantity of Kṛṣṇa's knowledge and your knowledge is different. He is full of all knowledge. You are almost full of all knowledge, but not exactly like Kṛṣṇa. And especially in your conditional life you are covered. All your knowledge is covered. Even that fragmental knowledge is also covered. Therefore you are in illusion.
Because we are fragmental, therefore we are subjected to be covered by the illusory spell. Just like the sky and the sun. Sometimes there is covering by cloud. The cloud covers a few miles or the cloud covers the eyes of living entities like us, but the cloud does not cover the sun or the whole sky. That is not possible. But a fragmental portion of the sky is covered by cloud, and because we are very teeny, if the cloud is spread only for ten miles we think, "Now the sun is covered." The sun is never covered. Similarly, the illusory energy cannot cover Kṛṣṇa, but it can cover you. And we are in this covering condition. Therefore we have forgotten our relationship with Kṛṣṇa.
Now we have to uncover by Kṛṣṇa's grace, or we'll have to go to the sunlight. It is not that the sun is covered by cloud. Where there is no cloud, if you go there, you'll get full advantage of the sunlight. Similarly, we have to search out place where there is no cloudy understanding. There must be clear understanding. Then you'll find yourself satisfied in the light.
