This is a extraordinary book of ideas of the mind. To grasp the meanings you will find it necessary to read (even more than twice) the various parts of the book. You will no doubt find the ideas different from Western writers of the mind, which sets this book apart from the many books about the mind.
A very intriguing book. Anybody who is interested in the mind and its functions from the Tibetan Buddhism point of view is highly recommended.
This book reviews several buddhist thought traditions that have developed through the time. It is somewhat polemical but is remarkable in that the referenced texts predate Kant, Hegel and other western thinkers delving the same subject. The book is tough to read but the reward is worth the effort because one comes to an awareness of what one goal of enlightenment is: the actual awareness of thought, origins of impressions, etc. Engrossing.
