Prabhupada: But that means that is not... Originally, it is from life. Seed is from the life. So where is your proof that matter produces life? Then you have to accept: life produces life. According to our sastra, within the semina of the father, the living body, living entity, takes shelter. And it is injected to the mother's womb and the two matters mixes and the body forms. This is our sastric explanation. Not that the semina discharged by the father, that is life. No. Within that semina, the living entity takes shelter. And it is put into favorable condition. Then it develops the body. This is... We, we find in Srimad-Bhagavatam. That putting of the living entity in a particular type of semina depends on higher authorities. The higher authorities will judge what kind of body this living entity, after leaving this body, will get. So by higher authority it will be directed to enter into the semina of such father, and it will be injected into the womb of the mother. Then you'll get, develop a particular type of body and come out and suffer or enjoy. This is the process.
Brahmananda: If that semina is misused or wasted, then that disrupts the plan of the authorities.
Prabhupada: Yes.
Brahmananda: It's a serious matter.
Prabhupada: Therefore this contraceptive method is sinful activity. Abortion, contraceptive method. This is against the, I mean to say, plan of the Supreme. Just like the government is making some plan, and if you spoil it, you are criminal.
