The more the whole self is involved, the realer one’s self is

Clearly, in the particular world we actually inhabit instinct and intuition are as essential to each thought, word, and deed as are sensation, emotion, and the intellect. Reason is as crucial to the poet as it is the philosopher, the sexual impulse is as necessary to the mother as it is to the lover. From the Zen perspective every real thought, word, and deed has its source in the whole self, thus the more the whole self is involved in one’s thoughts, words, or deeds, the realer (both truer and more existent) one’s thoughts, words, or deeds are.
