Tibetan Dzogchen: Christian origins? Resurrection and rainbow body

This paper offers another perspective on Christ's Resurrection through a comparative approach - anthropological, historical and theological - with the Tibetan Dzogchen tradition. This tradition reports numerous cases of "rainbow body" (tib. 'ja' lus), the disappearance of the physical body of their practitioners at the moment of death. Could this have something to do with the Resurrection, and if so, what? Thus, could the Dzogchen, whose historical origins date back to the 8th century, on the borders of Central Asia, Persia and Tibet, have been influenced by Syriac Christianity present at that time in these regions? Based on a study of a recent case of rainbow body in Tibet, we propose some avenues for reflection in the footsteps of the book of Fr. Francis V. Tiso, Rainbow Body and Resurrection.
