Hi again - I just went to look for your book on Marcus Aerelius and was delighted to see right in your introduction your understanding of the great "I AM," which - in my understanding of it - actually goes considerably deeper than Siegel's "Wheel of Awareness."
We use a preview and review of the day - from the context or perspective of what we call "open heartful awareness" (which actually touches on that great I AM) - in our course, "Train Your Brain, Change Your Life." We also draw a great deal on CBT, particularly in the 11th week of the course. https://www.remembertobe.life/12-week-e-course
I'm definitely going to read your book and follow Forge. Very good stuff!
