In Bhagavad Gita (9.26) the Lord said, “If one offers Me with love and devotion a leaf, a flower, fruit or water, I will accept it.” He accepts the offerings of devotees because of their transcendental love. Because they are in love with the Supreme Lord, they do not eat anything without offering it first to the Lord. The Lord does not hanker for a small leaf or flower; He has enough to eat. Indeed, He is feeding all living entities. Nonetheless, because He is very merciful and is bhakta-vatsala, in other words, He is always extremely pleased with His devotees very favorable to the devotees, He certainly eats whatever they offer Him with love and devotion.
