Krishna is Complete. Sad-aisvarya purnah. He is complete with full six opulences. He is the richest, He is the wisest, He is the most famous, He is the most strong, influential, and renounced order. Everything is complete there. Then why He is asking that patram puspam phalam toyam yo me bhaktya prayacchati? He is so rich, so opulent, still He is begging that "Little flower, a little water, a little fruit, if offered to Me with devotion and love, I accept and eat it." So the real fact is that we have lost our devotion, faith, in God. So He is begging therefore that love and faith. Not your money. Because He is already opulent. What you can give Him? And what belongs to you? Nothing belongs to you. You come from the womb of your mother openhanded, and when you die you go openhanded. So what does it belong to you? Nothing belongs to you. That's a fact. Simply by illusion, you come here for some days and you think, "This is mine." That's all. This is called maya. Actually, nothing belongs to you. Everything belongs to God, or Krsna. But you claim that it belongs to you. That is your maya. Therefore here it is said, manam janad avidusah karuno vrnite. Out of His causeless mercy He begs sometimes, "Give Me this." Just like sometimes father asks his child, "My dear boy, will you kindly give me a little cake from your portion?" And if the child is very fond of her (him), immediately gives. And sometimes he refuses, "No, I shall not give it." Similarly, Krsna is full. Why He's begging? He's begging your love. That's all. Whenever Krsna wants some service from you or begs something from you, it does not mean that He is in need of it. He is not in need of it. But He is in need of your love because you have forgotten how to love God, how to love Krsna. That he is practiced(?). There is a story that some sannyasi went to a householder, because a sannyasi goes to householder for begging. They are begging also like that. They are not beggars, but they introduce as beggar so that the householder may receive and take some advantage of his knowledge. He is not beggar. So one beggar went to a householder, and the housewife said, "Oh, this beggar has come from door to door. Give him some ashes." So the sannyasi replied, "All right. Give me some ashes. Just begin your charity." Just begin your charity. So similarly, Krsna, when He wants, "Give Me a little flower, a little fruit, a little water," it does not mean that He is begging. He is just inducing me to the practice of offering everything which belongs to Krsna.
