I have the book and have read most of it. It’s the best meditation guide I’ve ever read.
That said the end of Culadassas life and the struggles he went through jaded me a bit. IT showed me that someone can be the “best” At mediation and still kinda a crappy person. Stated another way - mediation doesn’t make you a good person and even someone who’s “enlightened” can do really bad stuff and hurt others.
