In the history of the devotees there was one devotee of Caitanya Mahāprabhu, Īśāna. So Caitanya Mahāprabhu wanted to give him some benediction. He was very poor man. Even his roof, thatched roof, that was not properly... There were so many holes. So Caitanya Mahāprabhu said, "My dear Īśāna, if you like, you can take some benediction." "No, why I shall take benediction?" "No, you have no roof even on your thatched house." He said, "Why? There are many birds. They are living on the tree. There is no roof at all. I have got roof with some holes, that's all. And they have no roof at all, so how they are living? For this purpose I shall ask You benediction? No, no, no." In this way he refused. So that is pure devotion, that "I shall not take any benediction from the Lord, but I shall give everything to God." This is. There is competition.
The Lord wants to give the devotee all opulences, and the devotee refuses to accept it. He wants to give his life and soul to the Lord. This is perfection. The gopīs, the gopīs, the ideal, the topmost devotee, they gave their everything to Kṛṣṇa, but they did not ask anything from Kṛṣṇa. Their honor, their body, their life—everything, sacrificed everything. Therefore Kṛṣṇa said to the gopīs that "I have no power to repay your debt. You be satisfied with your own activity. I cannot give you anything."
So this is the ideal devotion.
