What is the ascetic life for Nietzche?
self-denial, self-discipline: renoucement of worldly values and experiences, N is not competely against the ascentic ideals, but to be noble, you have to retain your passions and engage in self-denial. Deny your lower passions so that you can live by your higher passions. Part of that is willing to suffer over and over again for your passions and love. There is no God, so you have to create it yourself, destroy your values and recreate them day in and day out, living a form of ascetism (life of nobiilty)
