The first two parts (theoretical part) of the book are amazing, no one ever describe the why in any book, for example: he describes why bad emotions are poison to out body and they can drag illnesses. He also describes why it is easier for us to stuck in the suffering state. Lots more amazing explanations. However, I didn’t like the practical part (this is from my experience as spiritual teacher and councillor), the first reason is that he is suggesting meditating for 20 min at least daily, that is so much for beginner. If I want to reflect on my experience, I started with 3 minutes daily, and there were torturing for me, I increased these minutes upon my ….. . It took me a year to be able to increate it to 15 minutes. Still there are a lot of techniques in the practical part which are really good and helpful .
