This book is not for beginners. The reader needs to know the basic Buddhist concepts like emptiness, karma mechanism and so forth.
It is not a philosophical or religious book; rather than it is a technology description to achieve enlightenment through the realization of the emptiness of the mind according to Buddhism.
It puts together the essential points of this kind of path – described partially in other books -- and tries to connect them.
It is a book directed to Buddhist practitioners; it discloses important and basic concepts necessary to the practice.
The title agrees with the content. In my opinion, it must be read by all serious practitioners to clearly understand what enlightenment is and the steps of the practice. Other
aspects of this technique are described in the Dalai Lama’s books titled “Dzogchen” and “Mind in Confort and Ease”.
