My psychologist recommend me this book years ago. Indeed, I have just picked it up from my library.
I’m giving it a quick check now to refresh a little. My last note was at page 207 so I guess I quitted it there. If I remember well, l left it because the proposed exercises were more complicated that the single techniques I learnt to practise mindfulness. And I didn’t want to be more focussed on whether I was doing correctly the exercises than the aim of the exercise themselves, when I already have chosen the technique I found that suited better with me.

Said that, this therapy is part and based on the same principles of that so called Third Generation therapies that it’s to first be aware of thoughts and emotions that appears in our minds, accept them, not fighting against them in order not to feed them.
What happen with this? Which are the benefits? With practise, you learn to give these thoughts and emotions a relative relevance ( as a product of our over-protector brain) so once you get this, you are freer to go ahead with your life without having to carry a heavy burden. Your brain won’t ever be the same again. It will be working little by little as an alley. Not so over-protector. More objective and attentive to what’s really happening around you. It’s immense the plasticity of the brain.

You don’t need to believe the principles of this technique or therapy. You only have to give you a chance to experience it and you will see by your own.
