The article gives an account of shamanism in Nepal, particularly among the Tamang. The major social functions of the shaman in Tamang society is the diagnosis and treatment of illness. This article's main purposes are to investigate the indigenous categories of illness and examine the unique relationship that exists between modern medicine and shamanism in the Kathmandu valley of Nepal. It discusses the traditional categories of illness, like Lagu, and healing rituals, such as puja. It discusses the socio-psychology of the healing ritual practiced by Tamang shamans. The author argues that the shaman can even come to help spread medical aid in as much as they already recognize their own limitations in the treating of certain illness and take an active part in getting their clients to seek such treatment. Shamanism is not inherently antithetical to modern medicine. (Rajeev Ranjan Singh 2007-01-17)
