Rudolf Steiner:
62. In our sense-perceptions, the world of the senses bears on to the surface only a portion of the being that lies concealed in the depths of its waves beneath. Penetrative spiritual observation reveals within these depths the after-effects of what was done by souls of men in ages long gone by.
63. To ordinary self-observation the inner world of man reveals only a portion of that in the midst of which it stands. Intensified experience in consciousness shows it to be contained within a living spiritual reality.
64. The destiny of man reveals the workings not only of an external world, but of the man's own self.
65. The experiences of the human soul reveal not only a self but a world of the spirit, which the self can know by deeper spiritual knowledge as a world united with its own being.
