Yes thank you for this! The Power of Now is one of my favorite books.
One of the best things I learned from it was that my thoughts can just float by me without me grabbing onto them and being pulled like I'm holding an excited dog on a leash. I can just "sit on the park bench" in my mind, and allow them to pass me by, while I continue observing from my "bench".
This has drastically reduced my mental noise over the years and has helped me with meditation. This book goes so deeeep, (much deeper than I went here lol) and truly recommend it...it should be required reading in schools!
