Insight (vipassana) is "seeing things as they really are," which overcomes discursive thinking in favor of direct knowing or what is loosely translated as "intuition" rather than cogitating.

It means investigating in a systematic way AFTER having developed serene states of absorption (jhanas, zens, dhyanas) that one can enter and emerge at will.
