Unless Kṛṣṇa desires, unless He allows, we cannot do anything. We cannot do any... This is the fact. So tattva-vit... Tattva-vit means one who knows the truth. He thinks like that, that "I cannot do anything. I am always dependent on Kṛṣṇa. I cannot..." Mahatma Gandhi he used to say that "Not a blade of grass moves without the sanction of God." It is a fact. It is a fact. Nothing can be done without His sanction.
Then you can ask, "Then why somebody is doing bad work and why somebody is doing good work? In both ways Kṛṣṇa has sanctioned?" Yes, in both ways Kṛṣṇa has sanctioned. Without sanction he cannot do it. But how both ways Kṛṣṇa has sanctioned? Now Kṛṣṇa has sanctioned in this way. He has given you liberty. He has given you independence. Not full independence, but... You cannot become full independent. But you have got independence. He does not touch on your independence. That is there. Because otherwise, if you, if you are bereft of your independence, if you are without independence, then you have no meaning as living entity. Every living entity has got his minute share of independence. So Kṛṣṇa has given every one of you independence to make your choice. Now why you are...? Somebody is doing bad work or somebody is doing good work, and Kṛṣṇa giving sanction? How is that? That sanction is like that, that when I want to do something and I desire, I pray, "Oh, this thing may be done." It may be bad or good, that is a different thing. It may be... I am very much anxious. So when he's bent upon doing so, Kṛṣṇa gives him sanction, "Yes, you do it. You do it." He gives him facility. But one who has dovetailed himself into Kṛṣṇa consciousness, Kṛṣṇa gives him better consult, that "You do like this. Then you come to Me."
So sanction is always there. Sanction is always there. Without sanction, nothing can be done. So one who is in Kṛṣṇa consciousness he knows. He's tattva-vit. Tattva-vit means one who knows the truth, that "I cannot do anything without Kṛṣṇa's sanction."
