Valuable insights and knowledge about how to be a decent human being. I can always tell how much a book has moved me by how many Post-its I use to mark passages that speak to me. This book is pretty much flagged to death with Post-its. Here's one such wise passage:
"My mind, like everyone else's mind, falls into habitual, predictable traps. I get confused. Practice is not about never getting trapped. It's about recognizing traps and choosing freedom. If I pay attention, I won't get stuck forever. I'm determined to do it."
