So Krsna can see within our mind how much we are surrendered and how much we are after material enjoyment. Therefore the best thing is we have to make zero. Anyabhilasita-sunyam [Brs. 1.1.11]. Sunyam means zero. Unless we make everything zero, simply Krsna fact... Krsna is only fact, and everything zero. Without Krsna, everything zero. Just like one is one and, zero is zero, but when zero is added with one, it becomes ten immediately, ten times, similarly, this material world is zero, and Krsna is one. If you want to enjoy the material world by your own effort, it will always prove zero. You'll never be satisfied. But you add this zero by the side of Krsna -- you enjoy like anything, ten times. Ten times. With zero, it is zero, But when it is added with Krsna, it is ten times. Just see practically. Our Krsna consciousness movement was started with forty rupees. Now that forty rupees or something added with Krsna, it has become forty crores. You see practically. When I started for your country, I came to Mayapur. I offered my obeisances to my spiritual master, then I went. At that time I had no money even to purchase the ticket. And after that, I have come with forty crores. This is the secret. Ye yatha mam prapadyante [Bg. 4.11]. If you fully surrender to Krsna, then Krsna is there. You have to learn how to take from Krsna. Of course, a devotee is never desirous to take anything from Krsna. He wants to give only. This is pure devotee. A pure devotee wants, "Krsna, whatever little I have got, You take it, everything." And Krsna says, "Yes, because you have given your everything, even up to your life, I'll also give you My everything to you." This is Krsna.
