Rudolf Steiner,
The Philosophy of Spiritual Activity
“ No other activity of the human mind is so easily misapprehended as thinking. Will and feeling still fill the mind with warmth even when we live through them again in memory. Thinking all too readily leaves us cold in recollection; it is as if the life of the mind had dried out. But this is really nothing but the strongly marked shadow thrown by its luminous, warm nature penetrating deeply into the phenomena of the world. This penetration is effected by the activity of thinking with a spontaneous outpouring of power—a power of spiritual love. ”
