To be nonviolent to human beings and to be a killer or enemy of the poor animals is Satan's philosophy. In this age there is always enmity against poor animals, and therefore the poor creatures are always anxious. The reaction of the poor animals is being forced on human society, and therefore there is always strain of cold or hot war between men, individually, collectively or nationally.
A. C. Bhaktivedanta Swami PrabhupadaWhen a pure devotee or spiritual master speak, what he says should be accepted as having been directly spoken by the Supreme Personality of Godhead in the Parampara System.
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.
A. C. Bhaktivedanta Swami Prabhupada
