“A person must take care to exercise moderate discipline over the body and subject it to the Spirit by means of fasting, vigils, and labor. The goal is to have the body obey and conform — and not hinder — the inner person and faith. Unless it is held in check, we know it is the nature of the body to undermine faith and the inner person.”

The Tragic Sense of Life (1913), IX : Faith, Hope, and Charity
Original: (de) Wo die Produkte des spezifisch modernen Lebens nach ihrer Innerlichkeit gefragt werden, sozusagen der Körper der Kultur nach seiner Seele - wie mir dies heut gegenüber unseren Großstädten obliegt - wird die Antwort der Gleichung nachforschen müssen, die solche Gebilde zwischen den individuellen und den überindividuellen Inhalten des Lebens stiften, den Anpassungen der Persönlichkeit, durch die sie sich mit den ihr äußeren Mächten abfindet.
