Looking for this book by Dr. John Ott – “Health and light”
Hi Susan, Unfortunately Dr. Ott’s books are less and less available these days. They’ve become collector items to some degree. I did a google search and the only copy that I could find of HEALTH AND LIGHT for sale was $150.
Thank you for providing a source for this very hard to find book by John Ott.
What a Blessing!!!
Happy New Year Megann… thanks
Would love the complimentary PDF, some sites are selling this for 4000 US!!!
