a good approach to meditation

Interesting book - To soak up the state of mind necessary to address before embarking in the practice of meditation - Also gives tips for practice although in my case, I found sometimes it was a little vague and that advice given did not allow me to answer all my questions. In my view, essential book to understand what meditation is, what it entails in terms of thinking about yourself and change the world, the interest it may have for the individual and how to apprehend; he just ran me for some points, as very practical keys for the practice.
