Why are males and females physically attracted to each other? What is there in their physical appearance that makes them so excited that they want to be intimate, to the point where they consider this a great joy? The Sages of Israel understood the enormous power of sex and its immense challenges. Unlike other religions, such as classical Christianity, they never saw sexuality in a negative way. This is because sexual attraction is a reflection of Divine love.

And that is only possible when insight and creative inaction become one.
