At every step one has to wrestle for truth; one has to surrender for it almost everything to which the heart, to which our love, our trust in life, cling otherwise. That requires greatness of soul: the service of truth is the hardest service. What does it mean, after all, to have integrity in matters of the spirit? That one is severe against one's heart...that one makes of every Yes and No a matter of conscience.

Whenever the truth is uncovered, the artist will always cling with rapt gaze to what still remains covering even after such uncovering; but the theoretical man enjoys and finds satisfaction in the discarded covering and finds the highest object of his pleasure in the process of an ever happy uncovering that succeeds through his own efforts.

The heart and hand of those who always mete out become callous from always meting out.

Every man in creating the beautiful appearance of the dream worlds is a perfect artist.

For a tree to become tall it must grow tough roots among the rocks.

Your soul will be dead even before your body: fear nothing further.

Under peaceful conditions a warlike man sets upon himself.
