by Hanson through Professor Rev. Dr. James Kenneth Powell II, opensourcebuddhism.org This is a fine introduction to the Nying ma or “Old Ones” tradition of Tibetan Buddhism. We learn of the beginnings of Buddhism with this oldest tantric school from Padmasambhava through Longchenpa, arguably the greatest thinker of this school and Tsong kha pa’s arch-enemy. Wonderfully mystical school, the Nyingma is a favorite in the West mostly due to the fact that they do not keep the secrets so secret as do the other schools.
