"The mother keeps the baby in the stomach for nine months and then gives birth. She cleans her excreta and urine, and the child is [always] in this when he is small. Then that is [how] the mother takes care of the baby, doesn’t she? So she is Ganga Ma. All this trash, good things, bad things, everything, is in her. So she will never be impure. The mother is never impure."
