Gary Renard - My favorite A Course in Miracles author. All of his books have opened my eyes more and more to the true nature of the universe and how to ultimately end karma while practicing true forgiveness. His first book, The Disappearance of the Universe is highly recommended.
Kyle Gray - I love Kyle Gray’s approach to teaching about angels and how to work with them for spiritual information, protection, and guidance. I constantly use his card deck, Keepers of the Light, for a lot of my readings and I am a Certified Angel Guide through his online course.
