“Consider your eyes. They constantly move with motions called saccadic motion. If this is stopped artificially with a drug, you cannot see. Your eyes need the movement to provide contrasts and comparisons so your nervous system can construct your vision. It is the same with the mind. It seeks contrast and polarity. Since the mind is impersonal as well as personal, you find this search for contrast and extremes throughout nature.” Yogi Bhajan
