Age is not an excuse for giving up. If you allow yourself to grow passive and draw back, it’s a sign of personal defeat. There may be a retirement age at work, but there is no retirement age in life. How then could there be any “going into retirement” in the world of faith? The Buddhist Law is eternal, extending across the three existences of past, present and future, and one of the benefits of faith is perennial youth and eternal life.
