Lorraine Sinkler met Joel Goldsmith in 1949 before she had read any of his books, but knew at their first meeting that he would be her teacher. She later became the editor of most of his books and the Monthly Letters that were done until she stopped doing them in 1981. She worked with Joel closely both as a student of The Infinite Way and as editor of so much of his work.
She also opened The Infinite Way Study Center in Chicago and ran that for many years, at the same time developing the ability for spiritual healing and being a practitioner for many. She also was giving classes far and wide. When Joel died in England in 1964, Lorraine completed his schedule of classes.
