If you don't know yourself, you don't know your nature. If you don't know your nature, you don't know where to exist. By knowing your nature, knowing yourself, you know what to be and how to live. And that only comes from knowledge of self, knowing yourself.
RZALove is mistranslated into sex, because sex is not an expression of love. Sex is an expression of physical activity. It can be an expression of love between two people in love, but it's a carnal expression.
