Prabhupāda: ...identified with this material body. This is material life. Actually, I am spirit soul. I am not matter. Everyone can understand it, because the theory that living condition is developed under certain material condition. Just like we see sometimes that one germ is coming out the stool.
So people who are less intelligent, they say that the matter is producing a living being. There is another instance, vṛścika-taṇḍula-nyāya (nyāya-śāstra). Sometimes we see the scorpion is coming out from a heap of rice. So we are thinking that the rice is giving, generating, a life, and that is not fact. The fact is that the scorpions, they lay down eggs within the rice, and by the fermentation of the rice it..., a small scorpion come out.
So matter is not the cause of generating life. That's not a fact. Actually the living entity develops his body. Just like when there is sex intercourse, man and woman, the secretion mixes together; it becomes emulsified within the womb, and if the circumstances is favorable, then a living entity takes shelter of the secretion and the body develops. This is science. Not that the secretion itself in..., generating the body, generating the life. No.
