With direct language, Ashin Tejaniya conveys his ideas clearly. Some concepts could be further explored, like the notion of wisdom that he stresses so much, but I think that the vagueness is somewhat proposital, so you can "find your own answer".
There are also the non-secular stuff that I tend to skim over, because it's so hard to wrap around those ideas logically in my mind.
The format could get repetitive and boring sometimes, but due to that, I know understand his general principles a little more.
So I don't agree with everything, but the understanding that I got from it was really worth it. Gotta apply it practically instead of being satisfied with the theory, lest everything would be meaningless.
This is a wonderful book. I spent a long, long time reading it. It is absolutely not an "intro to mindfulness" book, and it reminds me of why it can be interesting, from time to time, to read a book by a monastic.
The primary reason to read this book is to get into greater depth in understanding the author's particular type of meditation practice and his personal philosophy on Buddhism. It was superb and amazing in those respects. The book was divided into three sections: one as answers to laypersons questions, another as a deeper discussion of some technical terms, and the last as aphorisms from the author. Now that I think about it, the book didn't really hang together in a compelling way, and that wasn't the point. Basically just a book for people who really like the author and his philosophy, and I count myself as one of them!
