ABSTRACT
Many present-day meditation masters teach only concentration, apparently convinced that this is all there is to meditation. If asked where insight fits into their scheme, they usually answer that insight will come of its own accord once concentration has been mastered. Some explain this by likening the mind to a deep pool of water, whose surface is constantly ruffled by the wind, so that one cannot see what lies beneath. Just as the sand, pebbles, and crabs at the bottom of the pool become visible once the surface movement subsides, so — it is said — the mind’s hidden deeper layers will be perceived once the superficial activity has been stilled through concentration practice.
