About fifty years ago, the late Venerable Mahasi Sayadaw of Myanmar introduced the technique of focusing one’s attention on the ‘rising and falling’ movement of the abdomen as an object to develop mindfulness. Thus meditators practise Satipatthana developing momentary concentration to achieve purification of mind, without the need to develop mundane jhana. Satipatthana Vipassana meditation became very popular among monks as well as the laity and many new Vipassana meditation centers sprang up all over the world to cater to the growing demand.
