Sin of birth control

Janananda Dasa: Prabhupada spoke to Kamaladevi's husband who was a doctor as follows; "If we are in this room, we require oxygen to breathe. Now if you spray poison in the room then we have to get out, we cannot survive. So, they poison the womb so that the child cannot take shelter there. It is poisoned and has to get out. That's what birth control is. People who perform this act have to take birth and suffer the same thing over and over again, from one womb to another to another. It is most sinful."
