Grab your copy of the Thin Within Book and walk through it with us. We will scrutinize the pages of this classic work and tell you what we, at Revelation Within, continue to celebrate and teach and what we have adjusted in our teaching at this time and why. Heidi, one of the teachers of this class, was the collaborator in writing this book with the Hallidays in 2001 and had the privilege of working closely with the Hallidays.
