Primordial Purity & Pure Appearance are two published volumes from a collection of talks given to tantrikas in 1987 by H.H. Dilgo Khyentse Rinpoche in Halifax, Nova Scotia, and Boulder, Colorado. Completely retranslated from the spoken Tibetan and lightly edited, these teachings are very inspiring and immediately useful in one’s practice. Pure Appearance, now in a second revised edition (2002), includes a discussion of the four abhishekas, the three samadhis, the six bardos, development stage practice (utpattikrama), and the four binding forces. Highly recommended.
Practicing this text requires being a tantrika. Please state the teacher, year and location, where you received pointing-out transmission.
