Swami replied: You can worship the snake as the symbol of God (Pratikaupasanam). You can also worship the snake as the incarnation of God (Sakshatupasanam). The second possibility is ruled out because God enters only the human form to preach the correct knowledge. The first possibility is also good in the case of beginners, who do not recognize the human incarnation due to ego and jealousy towards co-human forms. This is better than the worship of the statue because at least the first step of the address is accepted. A living being is better than a non-living item because God always incarnates in living beings only and especially in human beings because other living beings are incapable of understanding the spiritual path.
