The pure vision terma on which it is based teaches all Buddhist topics from the point of view of Dzogchen.

The Aro gTer terma was received by Western-born Buddhist, Ngakpa Chögyam.

His father was English and his mother German; he is distantly related to the composer Franz Schubert.

He studied Buddhism from the early 1970s through 1989, while working as a manual laborer, factory worker, and a truck driver in Britain to subsidize his education.

Dudjom Rinpoche gave the name Sang-ngak-chö-dzong to establish the western White Tantric Community organization,[5] which is located in Britain.
