This book is a tough read, it becomes very tricky to piece together certain understandings. I would suggest reading it twice. But the profundity is there. I have not read any other Shambala teachings, but the "Primordial Dot" has been very intriguing to meditate upon. Along with the awakening from the "shadow world" of the autonomous mind; this parralels other buddhist teachings. A nice addition to any collection, the hardcover is bleach white with the great eastern sun symbol in gold. It complements my Art of War hardcover which is completely black and the same size.
"The Great Eastern Sun" is presented as a companion volume to Chogyam Trungpa's spiritual classic "Shambhala: The Sacred Art of the Warrior."
Both books were based on Trungpa's talks, but "The Great Eastern Sun" has suffered (or benefitted) from a much lighter editorial hand. The result is that the present volume preserves a stronger flavor of Trungpa's teaching style. On the other hand, the talks in this book were intended for a more advanced audience who were presumed to be already familiar with the material presented in the earlier book.
My experience of Trungpa's books has always been one of a cumulative effect. It helps to read, to practice, to read again, and to practice some more. The extraordinary nature of the teachings grow clearer with time and practice, although sometimes very little comes through on the first reading.
