“ A man is now prepared to go beyond the mind, the heart, and hope, beyond his ego, his race, and mankind even, beyond all phenomena and plunge further into a vision of the Invisible permeating all things and forever ascending.
The essence of the Invisible is an agonized ascent toward more and more purity of spirit, toward light. The goal is the struggle itself, since the ascent is endless. ”
