BG Chap 9 - Kṛṣṇa's appetite for devotion
To worship the demigods, one has to perform elaborate sacrifices by numerous priests governed by intricate rules. Worshiping Kṛṣṇa is simple. If one offers Him with love and devotion a leaf, a flower, a fruit or water, He accepts it. His actual desire is to taste the bhakti of His devotee’s offering. The demigods are pleased by the offering; Kṛṣṇa is pleased by devotion. Thus Kṛṣṇa does not accept what is offered by non devotees with only some temporary devotion. The offering done by the devotee is out of love and not because someone told him to do it. One should have a pure mind and the sign of the purity of the devotee is they cannot give up service to Kṛṣṇa’s lotus feet. Even if there is a trace of lust or anger it is insignificant, like the bite of a toothless snake. The Lord enjoys the offering by eating the fruit and smelling the flower. Or being hungry and thirsty because of His love for the devotee, Kṛṣṇa eats everything that is offered without considering whether it is edible. Bhakti alone satisfies the Lord and not one’s status as a brāhmaṇa or one’s performance of great austerities.
A devotee not only offers these items to Kṛṣṇa with devotion but he bases his entire life on rendering pleasing service to Kṛṣṇa. Therefore, the essential ingredients of an offering (the sentiments of bhakti) are not only evoked at the time of the offering but are cultivated throughout a devotee’s life. The garden in which the grains, vegetables, fruits and flowers are sown and grown is watered with devotion to Kṛṣṇa. The flowers are picked and the food cooked with devotion. Finally, the items are served and offered to Kṛṣṇa. Kṛṣṇa says that He accepts (aśnāmi) such offerings because His devotee’s bhakti has given Him an appetite.
