Rainbow body (Tib. ja lü; Wyl. 'ja' lus) — fully accomplished Dzogchen practitioners can dissolve their body at the time of death.
- 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. ö ku), where the body transforms into light and disappears completely into space. This was done by Garab Dorje, Manjushrimitra, Shri Singha, Jnanasutra and Vairotsana.
- Another accomplishment of tögal practice is the ‘Rainbow Body of Great Transference’ (Tib. ja lü phowa chenpo; Wyl. 'jaj 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.
