the six transmissions [of Kama and Terma in the Nyingma Tradition]: rgyal ba dgongs brgyud, rig 'dzin brda brgyud, gang zag snyan brgyud, bka' babs lung bstan, smon lam dbang bskur, mkha' 'gro gtad rgya [RY]

sixfold transmission. To be endowed with the sixfold transmission means the mind, sign, and oral transmissions; as well as the transmissions of compassionate blessings, of dakini mandate, and of empowered aspiration. To be endowed with the ninefold transmission means with the addition of the transmissions of written yellow parchment, of profound pure vision, and of ultimate realization. Alternately, the yellow parchment can be substituted with the transmission sacrament that liberates through taste. In this way there are many variations. [RY]
