Ögyen yul-gi nub-chang tsam

"Ögyen is a name of a land. It is also a term which is used to indicate the origin of Vajrayana. Ögyen yul is an epithet for sem-nyid (sems nyid) – the nature of Mind. The word ‘tsam’, the last word of the first line of the Dorje Tsigdun, means juncture – the point instant of discovery. In common terms—according to mundane understanding, and with reference to our previous discussion—Ögyen yul, this green and pleasant land, is the place where we find what we have lost – the non-dual state."
