This work examines the ways in which the occult knowledge of plants is acquired and put into practice. This perennial wisdom animates many global spiritual traditions, especially those that have maintained their integrity of transmission. Often concealed within the deepest strata of the Western Esoteric Traditions, this green strand of wisdom, though obscured, is a potent legacy of all magic, sorcery, and occult science.  In addition to the hard sciences of botany, ethnology, agriculture and ethnopharmacology, a number of pathways can assist the magical herbalist in furthering the depth of understanding and integrity of personal approach.
