Rainbow body

In Dzogchen, rainbow body (Tibetan: འཇའ་ལུས་, Wylie: 'ja' lus, Jalü or Jalus) is a level of realization. This may or may not be accompanied by the 'rainbow body phenomenon'. The rainbow body phenomenon is pre-Buddhist in origin and is related to the indigenous Tibetan Bon religion,[1] and is a topic which has been treated fairly seriously in Tibet for centuries past and into the modern era. Other Vajrayana teachings also mention rainbow body phenomena which occur during or after the dying process.
