One could say that the introduction is too synthetic for someone with no perspective on the issue, too developed for those already interested. It would be a mistake. It has the merit of being honest and clarify the worldview that underlies the practical part. In the practical part of exercises, the text accompanying meditation puzzles me, I guess after trying to apply without changing anything, I would find my own words to accompany the child or children but for the moment This is just a guess :)
