Samten Migdrön (; alternate nomenclature) is a Tibetan text of historical importance for the historical relationship of Dzogchen and Zen as well identifying the view of its author, Nubchen Sangye Yeshe.
Namkhai Norbu et al. (1986: p. 23) identify Nubchen Sangye Yeshe as the author of a treatise, Samten Migdrön (Tib. bsam gtan mig sgron).[1]
Dalton (2003: unpaginated) in his introduction to the Anuyoga literature of the Nyingma states that:
Nubchen Sanggyé Yeshé is renowned for having preserved a number of tantric lineages through the so-called “dark period” of Tibetan history (roughly 842-978 C.E.), when state-supported monastic Buddhism fell into decline. Nubchen authored many works, including the Lamp for the Eye in Contemplation (bsam gtan mig sgron), an extensive discussion of early Tibetan contemplative systems.[2]
Samten Gyaltsen Karmay wrote on the Samten Migron.[3]
In the Samten Migdron, the 'Total Sphere' (thig le chen po) is described as having six aspects:
Karmay (2007: pp. 107–108) renders an extract of the Samten Migdron in English as follows (Tibetan set in Wylie has been included in References for probity, culled from page 108):
"Now, as for expounding the doctrine of Atiyoga, the excellent vehicle, the best and topmost yoga, the mother of all conquerors, its name is the Great Perfection. Why? Because it gives detailed teaching with a view to imparting direct understanding of the principle of this non-sought spontaneity with regard to all existential elements. The sense of the spontaneous essence, which is the innermost treasury of all vehicles and the great "universal grandfather" [spyi myes], is to be experienced directly by "self-awareness" [rang rig pas], but not as a thing to be kept in mind. It is to be made clear to the "self-awareness". How one is to know of it? In this vehicle of the high yoga, there is nothing that can be measured by the discriminative self-intellect as expounded in the tantras, authoritative works and precepts. Why is it so? Because all the so-called elemental particles have never grown new feathers or changed their colour from the beginning. It is the Buddha-nature, the "sphere of the great circle" [thig le chen po'i klong] of the "self-awareness". Who then has seen this as an object? Who has demonstrated the logic for seeing it? To what doctrine does one entrust it? With what cognition does one cognise it? All the elements are non-conceivable, because separately they have no substance."[5] [6]
