In Tibetan Buddhism, a tulku is a high-ranking lama, of which the Dalai Lama is one. A tulku is recognized as having the ability to choose the manner of his (or her) rebirth, although in normal circumstances a tulku would be reincarnated as a human of the same sex as before. A modern Chinese word for tulku is 'huofo', which literally means 'Living Buddha', although this term is rare outside Chinese sources.
