Litchi Tree

Now, the Lord Kṛṣṇa says that, “Anyone who offers Me in devotion these four things,” patraṁ puṣpaṁ phalaṁ toyam, “a bit of leaf and a bit of flower, a little fruit, a little water . . .” So He is pleased to take, accept. Why? Because we are offering Him with devotion and love. That is the only way. Just like if you offer me varieties of foodstuff and very palatable dishes, but if I am not hungry, then all these palatable dishes and varieties of foodstuff is useless. I cannot accept anything.
Similarly, if you offer anything to the Supreme Lord, He is full; He does not require your offering. He is always being served by hundreds and thousands of goddess of fortune. Lakṣmī-sahasra-śata-sambhrama-sevyamānam
(Bs 5.29).

We are, in the material world, we are seeking the favor of goddess of fortune, but in the spiritual world, hundreds and thousands of the goddess of fortunes, they are eagerly trying to serve the Supreme Lord. So He is full. He has nothing to accept from you. But He likes that you should offer Him something.
Just like a rich father: He does not like any help from the son, but if the son, after he is grown up, he is earning, and if he offers something to the father, oh, he becomes very happy. This is natural. So our connection with the supreme father is like that. He is not in want. He does not require anything from me. But it is for my interest. If I offer something, then I become a very pet son of my father. This is called bhakti. This is devotional service, or Kṛṣṇa consciousness. And why should we not offer? Then we are ingratitude. Suppose the father is supplying everything, and if I do not offer anything to my father, is it very good business? No.
