This book explains what inner work he led to achieve this, and that is within the reach of all. I confirmed the veracity of this possible inner work that leads to greater well-being, and have been for several months.
It also raises awareness that the very dark vision of man presented by Western philosophers for 1 or 2 centuries (Nietzsche explaining that without music, life would be a mistake; Freud saying: "From what I ' know [men] are for the most part of the scum ") is greatly nuanced and that unborn human being is not that bad.
You will understand, I can not recommend this book
