Oracles and Mediums
If "the lha is about to enter the subject's body and wants to communicate through this vessel. The body is the medium for the deity. In order for the lha to settle in the human body, the mind of the subject must be completely void. Once in the lha-state, the human becomes a lha, the deity himself. Since modern Western culture does not believe in spirits and deities, this bodily expression of a spiritual manifestation is regarded as a 'psycho-physical transformation of consciousness' (Schenk in Brauen, M. ed. Proceedings of the International Seminar on the Anthropology of Tibet and the Himalaya : Sept. 21-28, 1990. Ethnographic Museum of U. of Zurich, 1993.)
Chogyam Trungpa Rinpoche once told Jeremy Haward that "although there was great development of wealth in the Western world, through a lot of manufacturing, mining of the earth and so forth, much of the vitality of the land had been harmed, and because of that the dralas had departed."

In ancient Iranian mythology, the term deva or daeva is understood to refer to a demon. That is how English acquired the word devil. And the word ashura that signifies, in India, an opponent to the gods or Hindu devas, derives from the Iranian word Ahura (the s was dropped as a result of one of the characteristic transformations in the migration of vocabulary) that signifies the benevolent one of a pair of deities.
