David Christensen (Lama Urgyen Yeshe Ozer) is an Australian Lama of the Nyingma school of Tibetan Buddhism. David completed his traditional training in a 4 year retreat in Dordogne France during the 1980s under the guidance of his main teachers, Dilgo Khyentse Rinpoche, Dudjom Rinpoche, Nyoshul Khenpo and Tulku Pema Wangyal. He has spent over 30 years studying and practicing Buddhism in Australia, Nepal, France and the USA under some of the most influential Tibetan teachers of this century. David is also fluent in Tibetan and is highly regarded for his work in translating Dzogchen texts. As the founder of the Odiyana Centre, David provides a site for individuals to rediscover their own wisdom and health (the word health comes from holiness and wholeness) inspired by the wisdom energy of these ancient teachings.
