"Because the bhakta is offering He cannot refuse"

"There is a Vaṁsīdāsa Bābājī Mahārāja, he was talking with his Deity. And Kṛṣṇa... Just like Madana-mohana, He was talking with Sanātana Gosvāmī. Madana-mohana... Sanātana Gosvāmī at that time had no temple; he was hanging his Deity on the tree. So Madana-mohana was talking with him, "Sanātana, you are bringing all these dry capatis, and it is stale, and you don't give Me even little salt. How can I eat?" Sanātana Gosvāmī said, "Sir, where shall I go? Whatever I get I offer You. You kindly accept. I cannot move, old man." You see. So Kṛṣṇa had to eat that. (chuckles) Because the bhakta is offering He cannot refuse. Ye māṁ bhaktyā prayacchati. Real thing is bhakti. What you can offer to Kṛṣṇa? Everything belongs to Kṛṣṇa. What you have got? What is your value? And what is the value of your things? It is nothing. Therefore real thing is bhaktyā, real thing is your feeling. "Kṛṣṇa, kindly take it. I have no qualification. I am most rotten, fallen, but (begins to cry) I have brought this thing for you. Please take it." This will be accepted. Don't be puffed up. Always be careful. You are dealing with Kṛṣṇa. That is my request. Thank you very much."
