A spiritual master who is one hundred percent Krishna conscious is the bona fide spiritual master.
A. C. Bhaktivedanta Swami PrabhupadaOne has to ascertain the right path for his activities by following in the footsteps of great saintly persons and books of knowledge under the guidance of a spiritual master.
A. C. Bhaktivedanta Swami PrabhupadaBy the grace of the spiritual master the cloud of the mercy of the Personality of Godhead is brought in, and then only, when the rains of Krishna consciousness fall, can the fire of material existence be extinguished.
A. C. Bhaktivedanta Swami PrabhupadaOur first duty is to satisfy the spiritual master, who can arrange for the Lord's mercy. A common man must first begin to serve the spiritual master or the devotee. Then, through the mercy of the devotee, the Lord will be satisfied. Unless one receives the dust of a devotee's lotus feet on one's head, there is no possibility of advancement. Unless one approaches a pure devotee, he cannot understand the Supreme Personality of Godhead.
A. C. Bhaktivedanta Swami PrabhupadaOne 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.
