Carol Tuttle's book Remembering Wholeness is an amazing book. She really carries the true essence of joy. This book allows us to remember who we are and that we have always been whole, we just forget.
Marianne Williamson in her book Return to Love, is a powerhouse! She explains how everything boils down to LOVE, it is our core. It is what we are and what we are meant to be, love-based. It is a beautiful book!
