“After the destruction of the material body, this spirit soul is one. The spirit soul, due to contact with material nature, gets different types of bodies. When one can see this, he attains spiritual vision; thus being freed from differentiations like man, animal, big, low, etc., one becomes beautified in his consciousness and able to develop Krishna consciousness in his spiritual identity.” (Shrila Prabhupada, Bhagavad-gita, 13.31 Purport)
