Gelong Thubten is a Buddhist monk, meditation teacher and author from the UK. Gelong is a title meaning ‘senior monk’. Thubten was educated at Oxford University, and then became an actor, in London and New York. At the age of 21, tremendous amounts of stress led him to join a monastery. He ordained as a Tibetan Buddhist monk in 1993 at Kagyu Samye Ling Tibetan Buddhist Monastery. He has trained there under some of the world's most accomplished teachers of meditation, and has spent six years in intensive meditation retreats, the longest of which was 4 years.

Thubten specialises in teaching mindfulness meditation internationally, in businesses, hospitals, schools, universities, prisons and addiction counselling centres, and he gives keynote speeches at major events around the world. He has been teaching for over 20 years and is a world pioneer in the mindfulness movement, as he was teaching in these sectors many years before it became popular.
