I had the great blessing & Grace to be able to study closely with Hanna for many years in the 1970's through the mid-1990's. This particular book kept popping into my mind many times until I finally studied it closely. Hanna was a most dedicated, spiritually-minded healer who loved all. IMHO, it is well worth the time for anyone who is a serious truth-seeker to study & benefit from ALL her writings.
