Lama (Tibetan: བླ་མ་, Wylie: bla-ma; "chief" or "high priest") is a title for a teacher of the Dharma in Tibetan Buddhism. The name is similar to the Sanskrit term guru. Historically, the term was used for venerated spiritual masters or heads of monasteries. Today the title can be used as an honorific title conferred on a monk, nun or (in the Nyingma, Kagyu and Sakya schools) advanced tantric practitioner to designate a level of spiritual attainment and authority to teach, or may be part of a title such as Dalai Lama or Panchen Lama applied to a lineage of reincarnate lamas (Tulkus).
