Eighteen Marvels of Mind in Fifty Chapters

Eighteen Marvels of Mind in Fifty Chapters (sems rmad du byung ba bco brgyad kyi le'u lnga bcu). Several tantras in the first three volumes of the Nyingma Gyubum bear a resembling name although none of them have 50 chapters. A writing mistake seems to have appeared since The Bright Crystal Mirror by Yeshe Tsogyal says instead: “Five first parts of the Eighteen Marvels of Mind” (sems smad bco brgyad kyi stod kyi lnga), referring to the first five tantras translated by Vairotsana.
