The wisdom of old age is the fruit of a lifetime of living a moral life and practicing the discipline of a religious path. However, the effort which it takes to realize the fulness of spiritual wisdom should be undertaken from one’s youth. Strength and adaptability are required, and once old age has drawn nigh, it becomes too difficult to practice and too late to change. Old age is a time to manifest either the wisdom gained as the fruits of that effort or the decrepitude of a wasted life.
(from the book: World’s Scripture II)
