This ultimate stage of our spiritual exercise is called Silence. Not because its contents are the ultimate inexpressible despair or the ultimate inexpressible joy and hope. Nor because it is the ultimate knowledge which does not condescend to speak, or the ultimate ignorance which cannot.
Silence means: Every person, after completing his service in all labors, reaches finally the highest summit of endeavor, beyond every labor, where he no longer struggles or shouts, where he ripens fully in silence, indestructibly, eternally, with the entire Universe.

The Saviors of God (1923)
