Hindus and Buddhist believe that all beings die and are reborn in new bodies, or “incarnations.” While reincarnation is recognized across the Buddhist world, in the Tibetan Buddhist tradition, some important teachers (lamas) are thought to be able to control this process. Their successive incarnations, known as tulkus (emanation bodies), formed incarnation lineages such as Dalai Lamas, Panchen Lamas, Karmapas, and others.
