“And where is the boundary-if there is a boundary-between a collective outlook and "the world"?. Many cultures assume such a boundary, but they set it in different places. Divine appearances once were real- they are mere fantasies today. Where shall we, who examine the phenomenon, set the boundary?”

The Saviors of God (1923)
Context: I will not accept boundaries; appearances cannot contain me; I choke! To bleed in this agony, and to live it profoundly, is the second duty.
The mind is patient and adjusts itself, it likes to play; but the heart grows savage and will not condescend to play; it stifles and rushes to tear apart the nets of necessity.
