"The logic of the four seals superb"

The author is very familiar with Western society which allows it to use images and examples very "talking" for a player who is not from a Eastern / Buddhist culture. This makes it easy to read and understandable concepts. Add to this, a simple style, an excellent translation, and a good dose of humor and you have an excellent book. Simplify to make it more accessible and at the same time more "strict", more "just", the Buddha's teaching, that is the wish of the author and he succeeded pretty well. But no mistake, behind an apparent simplicity, "is not Buddhist who wants to."

Upon introduction, Dzongsar Jamyang Khyentse said that being Buddhist is to accept the truths 4 / following seals:
- All composed things are impermanent
- All emotion is pain
- No thing exists in and of itself
- Nirvana is beyond concepts
(Not to be confused with the 4 Noble Truths that only treat of suffering)
From there, he will constantly throughout the book to come back and explain each of these truths. An excellent introduction for those who want to better understand the fundamentals of Buddhism.
