- Through the practice of trekchö, the practitioner can attain the so-called ‘rainbow body’, in which the body becomes smaller and smaller as it dissolves, emanating rainbow light, and finally only the hair and nails are left behind.
- Through the practice of tögal, the practitioner can dissolve his or her body into the ‘Light Body’ (Tib. འོད་སྐུ་, ö ku),
- Another accomplishment of tögal practice is the ‘Rainbow Body of Great Transference’ (Tib. འཇའ་ལུས་འཕོ་བ་ཆེན་པོ་, ja lü phowa chenpo; Wyl. 'ja lus 'pho ba chen po),
where the master dissolves his body into rainbow light and lives for centuries in order to benefit others. Such was the case with Padmasambhava, Vimalamitra, Nyang Tingdzin Zangpo and Chetsün Senge Wangchuk.
