Asceticism is an instinct which the most noble, the strongest among men have felt : It is a fact, it must be taken into account if the value of life is to be appreciated.
Asceticism is an attempt to suppress all feeling and even the ego as an antidote to the melancholy and inferiority that plague the weak by distracting the mind and filling the day with activity.
Asceticism is a good thing as long as it is honest, that is, as long as it does not deceive itself (as it does for the ascetic priest) by resting on some kind of metaphysical idea that suffering now will result pleasure in some otherworldly life.
Confucius say ... man who sleep on bed of nails only real holy man
Asceticism is able to provide the means for enhancing one's actual life and for affirming it more strongly. It is produced by a desire and a tendency, perhaps even a compulsion, to engage in what one is best suited for, regardless of the consequences: It is the product and expression of the will to power... its meaning is the will to power.
Asceticism is affirmative of life in the extreme when it is expressive of the desire to transform being not by escape into the otherworldly but by inserting oneself ever more deeply into the crevices of time and fissures in space.
Asceticism is a rejection of embodiment... originating in such doctrines as augustine's original sin, it paints the world as fallen and seeks to transcend the world through mortification of the flesh or in (as in the story of Jesus) death.
Asceticism is grounded in looking for and finding satisfaction in failure, decay, pain, misfortune, ugliness, voluntary deprivation, destruction of selfhood, self-flagellation and self-sacrifice.
