"It must be understood that the silence referred to by the adjective ‘mystical’ is not external, esoteric silence, intended to conceal secret truths from the ‘uninitiated’, but rather inner silence, which consists in silencing one’s thoughts, however profound they may be, and therefore in detachment, especially from all our supposed knowledge. Detachment is the work of intelligence, which incessantly recognizes the finiteness of its own contents and, at the same time, of the will, which incessantly recognizes in those same contents the presence of egoism, of that amor sui that is truly the root of all evil."
