I read your review carefully and was impressed by your intelectual capacity and logic of your reasoning. Thank you.
As a Buddhist practitioner (for 9 years, not necessary with goats in the mountains but anywhere and anytime one can access their mind - place is irrelevant) I would like to clarify for other potential buyers that "resting in mind's nature" is an ultimate goal of Buddhist practice and it would eventually bring up the experience of realization of full mind's potential which is enlightenment.
As you can not have the experience of being pregnant just by reading a book about pregnancy neither "The Tibetan Book..." is aiming to give you the experience of what is described there.
What is given is the information and hopefully an inspiration to apply the ideas in you everyday life. Nothing more.
Since some very practical concepts are easy and can be applied by anyone without any difficulties when it comes to fruition of human potential it will appear far more difficult than, let's say, getting pregnant :-)
That is why the author responsibly tells the truth: you can learn to ride a bike just by reading the instructions since learning to fly a jet is possible but only after significant training is given by an experienced pilot!
Lucky we all have minds (!?!) and can choose how fast we need to ride those. And since so little knowledge is given about our mind by wonderful education systems of our western world anything we can learn about it is great. Even with bike's speed going forward is so much more meaningful than going circles all the time. Cruising is also pleasant and refreshing :-)
This book can be of great help particularly for people getting ready to die by simple tips how to lead yourself through the most unknown journey waiting for all of us at the very end of our lives. The highest potential described can be achieved by everyone who will feel inspired to learn
the way things are in practice and "The Tibetan Book of Living And Dying" can be a quality starting point if one wishes to do so.
