ZEN  does not have any GOD, that's its beauty.  But it has a tremendous science to transform your consciousness, to bring so much awareness to you that you cannot commit evil.  It is not a commandment from outside, it comes from your innermost being.  Once you know your center of being, once you know you are one with the cosmos - and the cosmos has never been created, it has been there always and always, and will be there always and always, from eternity to eternity - once you know your luminous being, your hidden Buddha, it is impossible to do anything wrong, it is impossible to do anything evil, it is impossible to do any sin.
