• By its very nature every embodied spirit is doomed to suffer and enjoy in solitude. Sensations, feelings, insights, fancies—all these are private and, except through symbols and at second hand, incommunicable. We can pool information about experiences, but never the experiences themselves. From family to nation, every human group is a society of island universes. (p. 3)
  • The mind is its own place, and the places inhabited by the insane and the exceptionally gifted are so different from the places where ordinary men and women live, that there is little or no common ground of memory to serve as a basis for understanding or fellow feeling. Words are uttered, but fail to enlighten. The things and events to which the symbols refer belong to mutually exclusive realms of experience. (p. 3)
  • To see ourselves as others see us is a most salutary gift. Hardly less important is the capacity to see others as they see themselves. (p. 3)
  • Space was still there; but it had lost its predominance. The mind was primarily concerned, not with measures and locations, but with being and meaning. (p. 6)
  • The function of the brain and nervous system is to protect us from being overwhelmed and confused by this mass of largely useless and irrelevant knowledge, by shutting out most of what we should otherwise perceive or remember at any moment, and leaving only that very small and special selection which is likely to be practically useful.” (p. 7)
  • In the final stage of egolessness there is an “obscure knowledge” that All is in all—that All is actually each. This is as near, I take it, as a finite mind can ever come to “perceiving everything that is happening everywhere in the universe.” (p. 8)
  • One ought—but in practice it seemed to be impossible. This participation in the manifest glory of things left no room, so to speak, for the ordinary, the necessary concerns of human existence, above all for concerns involving persons. For persons are selves and, in one respect at least, I was now a Not-self, simultaneously perceiving and being the Not-self of the things around me. (p. 11)

  • The sum of evil, Pascal remarked, would be much diminished if men could only learn to sit quietly in their rooms. (p. 14)
  • To be shaken out of the ruts of ordinary perception, to be shown for a few timeless hours the outer and the inner world, not as they appear to an animal obsessed with survival or to a human being obsessed with words and notions, but as they are apprehended, directly and unconditionally, by Mind at Large—this is an experience of inestimable value to everyone and especially to the intellectual. (p. 25)
  • But the man who comes back through the Door in the Wall will never be quite the same as the man who went out. He will be wiser but less cocksure, happier but less self-satisfied, humbler in acknowledging his ignorance yet better equipped to understand the relationship of words to things, of systematic reasoning to the unfathomable Mystery which it tries, forever vainly, to comprehend. (p. 27)
