More than fifty books have been compiled from Joel S. Goldsmith s tape-recorded lectures and class work, feeding a worldwide student body which continues to practice and preserve his work. The Heart of Mysticism contains the monthly letters written by Joel in Hawaii and sent to students from 1955 to 1959. Originally published as individual volumes for each year, this collective edition is the most comprehensive anthology of Joel s material available today. From these lessons readers can now follow the spiritual mind of one of the great mystical writers from the last hundred years.
