Namkhai Norbu Rinpoche - The Mirror
I am sure this has been here before, but here are 2 versions of this teaching.
The Mirror is a concise and straightforward introduction to the Tibetan Buddhist practice of Dzogchen, "The Great Perfection".
To insure the survival of Dzogchen outside of Tibet, this precious and long-secret teaching has in recent years been taught openly by great masters cast abroad by the Tibetan diaspora. In The Mirror, Namkhai Norbu Rinpoche presents the quintessence of this most sophisticated and refined, yet pristinely simple and direct path to spiritual attainment.
When I first attended teachings with the Dzogchen community, a member gave me the paperback book of this. It also includes an introduction and a commentary, which I hope to share soon.
I believe one pdf is the original translation into English, the other is a freshly revised copy I found online.
