It is also good to practice 1-2-3-4-5-6-7-8-7-6-5-4-3-2-1. These four immaterial jhānas will deepen your concentration so that you have a mind that is even more concentrated, purer, brighter, more malleable, wieldier, steadier, and more imperturbable. This will enhance your insight practice by enabling you to have an even less egocentric viewpoint and maintain it for an even longer period of time.
