Brother Dassana has been practising Vipassana Meditation for over 20 years. He has done many years of retreats in Burma, Thailand and Malaysia under various teachers. Most of his retreats are in the Mahasi style, though he has also explored other traditions. He was a monk for 17 years, and this gave him the opportunity and time to study the Dhamma scriptures and to do long intensive Vipassana retreats.
