Hayagrīva: James gave the following estimation of impersonalism and Buddhism. He wrote, "There are systems of thought which the world usually calls religious and yet which do not positively assume a God. Buddhism is in this case. Popularly, of course, the Buddha himself stands in place of a God, but in strictness, the Buddhistic system is atheistic."
Prabhupāda: Yes. That is described in the Śrīmad-Bhāgavatam, sammohāya sura-dviṣām (SB 1.3.24). Lord Buddha appeared at a time when people became atheistic, and especially they began to kill animals in the sacrifice in large quantity. So God, Lord Buddha, appeared, being sympathetic to the poor animals. Sadaya-hṛdaya darśita-paśu-ghātam. He was very, very much aggrieved to see the poor animals are being killed unnecessarily. So he preached the religion of nonviolence, and because the people became atheist, so Lord Buddha, just to take them under his control, he also collaborated and said, "Yes, there is no God, but you hear me." But he is incarnation of God, so it is a kind of transcendental cheating that in the beginning he said there is no God, but he is God himself, and people accepted his words or instruction. That is Buddhism. So this very word is used, sammohāya sura-dviṣām (SB 1.3.24). Sura-dviṣām, atheist class of men, are always against theist class of men. Therefore their name is that atheist means who are envious of devotees. So in order to cheat these persons who are envious of God or devotee, Lord Buddha appeared and established a system of religion on the platform of nonviolence—no more animal killing. Because those who are animal killers, they cannot understand God (indistinct). That is not possible. They may have some vague idea. So Lord Buddha wanted to stop these sinful activities, and he established the system of nonviolence.
