转世 is a Buddhist concept referring to the process of being reborn into a new life after death. It's used both as a noun ('reincarnation') and a verb ('to be reborn'). In Tibetan Buddhism, it specifically describes the recognized reincarnation of high lamas (e.g., the Dalai Lama or Panchen Lama). Unlike Western 'reincarnation,' 转世 often emphasizes a purposeful, guided rebirth of enlightened beings for the benefit of others.
