Middle Drukpa
"From Tsangpa Gyare, in relation to the three primary places in which the teaching stayed, three lineages came to be spoken of — 'The Upper', 'The Lower' and 'The Middle' Drukpa Kagyu. These were the primary places of residence of the teachers and the lineage but principally were the places where many teachings of the profound-and-vast view, meditation, and action were present."
"In recent times of great trouble, all of the teachings of the Middle Drukpa lineage have a deteriorated significantly and at this point, in order quickly to protect the textual tradition which has become devastated, all of the profound sections of the Drukpa Kagyu are being gathered into one place and arranged into a six-part collection."[1]
