The holy name of Krishna is so attractive that anyone who chants it — including all living entities, moving and nonmoving, and even Lord Krishna Himself — becomes imbued with love of Krishna. This is the effect of chanting the Hare Krishna maha-mantra.
Chaitanya Caritamrta, Antya Lila 3.268,
Krishna, known as Govinda, is the Supreme Godhead. He has an eternal blissful spiritual body. He is the origin of all. He has no other origin and He is the prime cause of all causes.
Sri Brahma Samhita 5.1
The ultimate goal of Bhakti is to get Krishna and we get it by taking shelter of the holy name.
Krishana is very kind. Therefore, He has given us his remnants of food stuff.
