Since coming to the West in 1982, and later becoming both a resident in Italy and and eventually an Italian citizen, Lama Gangchen's activities have taken on an ever increasing worldwide scope towards the achievement of World Peace. Mainly, it began with the founding of: The Kunpen Lama Gangchen Institute for the propagation and preservation of the Tibetan Medical Tradition in Milan, Italy in 1989. Here Lama Gangchen has initiated the first extensive programmes of Himalayan medical and astrological studies for Western students. Also concerned with the preservation of the Himalayan culture, the centre holds courses in Buddhist philosophy, thanka painting and other arts. Lama Gangchen has invited many groups of Tibetan monks to Europe such as the Ganden Shartse monks, the Sera-Me monks, the Nyalam Phengyeling monks and the Segyupa monks to make sand mandalas and perform sacred Cham dances; all of their activities are dedicated to world peace. The Institute is also the Western Headquarters of Lama Gangchen's activities and his Western residence. The Lama Gangchen World Peace Foundation (L.G.W.P.F.), International Friendship for the Support of Tibetan Medicine, Vajrayana Buddhist Philosophy and Self Healing to Develop World Peace, established in 1992 following an International conference of doctors, healers and therapists held in Milan, Italy. The Foundation has its main seat in Spain and was officially recognised by the Spanish government in November 1993. Each year the L.G.W.P.F. holds an International congress m Madrid, Spain, which provides a forum for discussion between scientists, doctors, therapists and philosophers. One of the major aims of the Foundation is to provide documented scientific evidence about the benefits of ancient Tibetan Himalayan healing methods, other natural healing methods and the energetic qualities of spiritual healing. The Foundation also gives a base for constructive dialogue between different cultures in order to create and promote educational methods to develop Inner Peace and World Peace.
