The term 'HE'S A PRIEST' can be solved by the four letter word 'LAMA'. A LAMA is a Tibetan Buddhist priest, and is a title for a spiritual leader. The title is used to refer to a monk of the Gelug or 'Yellow Hat' school of Tibetan Buddhism, which is the newest of the schools of Tibetan Buddhism. Lamas are believed to be reincarnations of past religious teachers, and they are responsible for teaching Buddhist doctrine and leading religious ceremonies.
