Fulfillment mode yogas
dream yoga, the yoga of the mystic heat, Mahamudra meditation, the yoga of the apparitional body, the yoga of resurrection, clear light meditation,
and the yoga of uniting skillful means (upaya) and perfect insight (prajna) to create the seed-essence of pure pleasure.
"Seed-essence" is a rendering of tigle and changchubsem = 'seed-essence' = yang life-force = white bodhicitta.
Seed-essence (Sanskrit: bija-tattva) is cognate with bindu (Sanskrit) and gankyil (Tibetan).
Dowman further maps the instrumentation of "fulfillment meditation" in relation to the Mahamudra kundalini raising of the 'phowa of Great Transference' ("ultimate liberation") through the cranial fontanelle at the 'Bardo of Death' and a subsidiary preparatory sexual yoga.
