In the light of these facts, we are able to understand what asceticism is, what place it occupies in the religious life and whence come the virtues which have generally been attributed to it. In fact, there is no interdict, the observance of which does not have an ascetic character to a certain degree. Abstaining from something which may be useful or from a form of activity which, since it is usual, should answer to some human need, is, of necessity, imposing constraints and renunciations. So in order to have real asceticism, it is sufficient for these practices to develop in such a way as to become the basis of a veritable scheme of life. Normally, the negative cult serves only as an introduction and preparation for the positive cult. But it sometimes happens that it frees itself from this subordination and passes to the first place, and that the system of interdicts swells and exaggerates itself to the point of usurping the entire existence. Thus a systematic asceticism is born which is consequently nothing more than a hypertrophy of the negative cult. The special virtues which it is believed to confer are only an amplified form of those conferred, to a lesser degree, by the practice of any interdiction. They have the same origin; for they both rest on the principle that a man sanctifies himself only by efforts made to separate himself from the profane. The pure ascetic is a man who raises himself above men and acquires a special sanctity by fasts and vigils, by retreat and silence, or in a word, by privations, rather than by acts of positive piety (offerings, sacrifices, prayers, etc.). History shows to what a high religious prestige one may attain by this method: the Buddhist saint is essentially an ascetic, and he is equal or superior to the gods.
