Dowman travelled to India and Nepal in 1966 where he practiced Kriya Yoga with Ganesh Baba and vipassanā meditation with the Indian Theravadin teacher Anagarika Munindra. After connecting with Tibetan Buddhism, he met and trained under many Tibetan masters, including his root gurus Dudjom Jigdral Yeshe Dorje and Kangyur Rinpoche, Longchen Yeshe Dorje. He lived near these masters in Darjeeling, West Bengal, for many years. He studied Classical Tibetan at Queens College, Sanskrit University, in Varanasi, India, under Lama Jamspal. In 1973, at the Nyingma Institute in Berkeley, California, his translations were first published under the auspices of Tarthang Tulku, while he taught on Tibetan language at Sonoma State University.
Dowman has written books and translations focusing on various aspects of Tibetan Buddhism and Tibetan culture including travel literature in particular on Vajrayana and Dzogchen. In his later writings, he has focused increasingly on Dzogchen and in particular on the works of the 14th Century Nyingma master scholar Longchenpa.
Since 1993 he has been teaching and leading retreats on Vajrayana and Dzogchen throughout the world.

- In his Foreword to Natural Perfection: Longchengpa's Radical Dzogchen Namkhai Norbu writes, "Kusho Keith Dowman, the translator of this text, has spent many years living in India and Nepal in communion with many great masters who have realized the Dzogchen view. Studying within their purview, fully immersed in the sacred teaching, he has fortuitously absorbed the realization of Dzogchen. Now he has translated this extraordinary text, The Treasury of Natural Perfection, and if it can become part of the lives of fortunate practitioners, its inestimable value will become immediately apparent."
