One who loves Krishna will give Him whatever He wants, and he avoids offering anything which is undesirable or unasked for. Thus, meat, fish and eggs should not be offered to Krishna...Vegetables, grains, fruits, milk and water are the proper foods for human beings and are prescribed by Lord Krishna Himself. Whatever else you eat, can not be offered to Him, since He will not accept it.

A. C. Bhaktivedanta Swami PrabhupadaThe Lord has different names according to His different activities. For example, His name is Madhusรผdana because He killed the demon of the name Madhu; His name is Govinda because He gives pleasure to the cows and to the senses
A. C. Bhaktivedanta Swami PrabhupadaOut of many millions of wandering living entities, one who is very fortunate gets an opportunity to associate with a bonafide spiritual master by the grace of Krishna. By the mercy of both Krishna and the spiritual masters, such a person receives the seed of the creeper of devotional service.
