The practice involves systematic observation of bodily sensations with equanimity, developing insight into the impermanent, unsatisfactory, and selfless nature of all phenomena. Practitioners sit quietly, observing the natural breath and scanning the body from head to toe.
The technique requires no conversion to Buddhism or acceptance of any belief system. It is a practical method for purifying the mind through direct experience. Regular practice develops concentration and equanimity, leading to deeper insights into the nature of reality and the causes of suffering.
Vipassana is typically taught in 10-day residential courses where students maintain noble silence and follow a structured schedule of meditation, with sessions beginning before dawn and continuing through the evening.
