Who is Edgar Cayce famous for?

Do you mean "what is Edgar Cayce famous for?" He is mostly famous for his holistic medical cures. Beyond that some see his readings as a way to connect with our true selves. I will not elaborate on that. However, when I had mive cysts, instead of surgery, I resorted to castor oil packs, first recommended by Cayce. Now, two years later, they have subsided and my exams show no problems. I believe he had a perspective that few of us will ever realize. This does not mean he was right about everything. Being an imperfect human he made mistakes and may have even been influenced by negative forces. Cayce was a devout Christian.
