In the example of the dragon girl, it is worthy of considering how prejudices can enter our way of thinking and influence us in negative ways. Because a woman bleeds, which is the result of giving birth, she was considered impure, and yet giving birth, bringing new life into the world is one of the purest things. I once heard someone say that women bleed giving birth and men bleed killing. Perhaps we should give this some thought. Nichiren wrote a response to a woman believer saying that because a woman bleeds she is considered impure by society, but in the eyes of the Buddha that distinction does not apply.
