The car is driven by means of a wheel which is inside it; when that wheel is turned, the outer wheels move. So also, the inner wheel has to be turned in man, so that he may progress. Trying to move to outer wheels is a sign of ignorance; it is a waste of precious energy. Inner concentration is to be developed in preference to outer distraction. Quietness, simplicity, humility… cultivate these, instead of noise, complexity, conceit.
