Our aim must be all-round development--a sane, healthy, balanced life. Meditation is not enough, albeit essential in its place. The cultivation of a sharp keen intelligence for philosophical reflection is just as essential. The two must work hand in hand, with a perfect development of each ideal as the goal. The kingdom of heaven is in the head as well as the heart.
