Maturity, according to Osho, is not to grow old but to grow up. To grow old is to move in the horizontal dimension, accumulating more and more knowledge, more and more experience. But to grow up is to take a step into the vertical dimension, where maturity is measured not in years but in serf-sufficiency, wisdom and integrity. Maturity is the joyous and peaceful flowering of the human spirit.
