“I live not in myself, but I become
Portion of that around me: and to me
High mountains are a feeling, but the hum
of human cities torture.”

Context: I needed to sing — desperately. My voice poured out more easily because I was no longer singing for anyone's approval; I was beyond caring about the public's reaction, I just wanted to enjoy myself. … I had found a kind of serenity, a new maturity, as a result of my childrens' problems. I didn't feel better or stronger than anyone else but it seemed no longer important whether everyone loved me or not — more important now was for me to love them. Feeling that way turns your whole life around; living becomes the act of giving.

Kulturphilosophie (1923), Vol. 2 : Civilization and Ethics
Context: Affirmation of the world, which means affirmation of the will-to-live that manifests itself around me, is only possible if I devote myself to other life. From an inner necessity, I exert myself in producing values and practising ethics in the world and on the world even though I do not understand the meaning of the world. For in world- and life-affirmation and in ethics I carry out the will of the universal will-to-live which reveals itself in me. I live my life in God, in the mysterious divine personality which I do not know as such in the world, but only experience as mysterious Will within myself.
Rational thinking which is free from assumptions ends therefore in mysticism. To relate oneself in the spirit of reverence for life to the multiform manifestations of the will-to-live which together constitute the world is ethical mysticism. All profound world-view is mysticism, the essence of which is just this: that out of my unsophisticated and naïve existence in the world there comes, as a result of thought about self and the world, spiritual self-devotion to the mysterious infinite Will which is continuously manifested in the universe.
