Fifty Years in The Summit Lighthouse with Mark L. and Elizabeth Clare Prophet. Mary Ellen Lee recounts her experiences with Mark and Elizabeth Clare Prophet and teaching the Montessori Method.
You'll find this quote on the first page of the book:
"I just finished reading your memoirs and they were like a spiritual guidebook, a handbook on the path for me and I learned so much. You are a special soul to have been such a faithful chela and friend to Morya, Mark and Mother. Your dedication to the Path and the lifetime of service to support Mother and to spread Mother Mary's and Maria Montessori's teachings on education far and wide throughout the world are inestimable. I AM blessed and grateful to know you." —N.Y. Publishing Coach
