Bardo Thodol
The Five Pure Lights are also evident in the terma traditions of the "Bardo Thodol" (Gyurme, "et al." 2005) where they are the "coloured lights" of the bardo for example, associated with the different "families" (Sanskrit: gotra) of deities. There are other evocations of the rainbow lights as well in the "Bardo Thodol" literature such as Namkha Chokyi Gyatso (1806-1821?), the 3rd Dzogchen Ponlop's "Supplement to the Teaching revealing the Natural Expression of Virtue and Negativity in the Intermediate State of Rebirth", entitled "Gong of Divine Melody" (), wherein the "mandala of spiralling rainbow lights" Gyurme "et al." (2005: p. 339) is associated with Prahevajra. Dudjom, "et al." (1991: p. 337) ground the signification of the "mandala of spiralling lights" () as seminal to the visionary realization of tögal.
