"When I leave the Church and the city behind and go out under the sky, when I am with the birds, [...] with the clouds, [...] and with the oceans, [...] I cannot feel Christianity because I am in a world which grows from within. I am simply incapable of feeling its life as coming from above. More exactly, I cannot feel that its life comes from Another, from one who is qualitatively and spiritually external to all that lives and grows. On the contrary, I feel this whole world to be moved from the inside, and from an inside so deep that it is my inside as well, more truly I than my surface consciousness."
