Reading the text one can definitely get a lot of insights into the deepest teaching of the planet(if not the universe)... Prejudice apart, the book IS a real thing taught by eminent Lonchenpa and translated into English with a high degree of precision. Thumbs up!
Longchenpa was the great systematizer and transmitter of Dzogchen and his writings combine visionary poetic expositions of the nature of reality with lucid explanations and practical advice. He's one of the greatest Buddhist masters of all time. A true genius in every sense of the word. If you read his more esoteric books you will be astounded at the clarity and brilliance of his mind. This book is one of his most accessible texts -- it is essential for anyone practicing Dzogchen because it focuses on integrating the practice with ordinary daily life. The translation is especially accurate having been approved by Namkhai Norbu, one of the most eloquent and erudite contemporary Dzogchen teachers. It's a definite must-have for anyone interested in Tibetan Buddhism and in particular Nyingma philosophy and Dzogchen. It's also a great text for anyone trying to integrate their spirituality into daily life.
