Although being a regular meditation, positive affirmations, I learned a lot with this little book so dense.
A small price, if there was a book to give to get better, this would be it.
A great quantity and diversity of proposed concrete exercises (creation of the inner sanctuary, meeting his guide, healing meditations ...). Some proposed in addition to taking his pencils (treasure map, great painting ...).
For beginners the basics and principles of visualization seem very well explained to me.
