Occultism Simplified: The Mystic Thesaurus

First published in the late 19th century, Occultism Simplified: The Mystic Thesaurus by Willis Whitehead serves as both a guidebook and a lexicon of hidden knowledge. Designed for seekers at the threshold of the occult sciences, it distills the vast body of mystical traditions into clear and accessible form without stripping them of their mystery or danger.

Within these pages are entries and explanations covering alchemy, astrology, magic, spiritualism, and esoteric correspondences—a reference for the words, symbols, and principles that form the language of the unseen. More than mere definitions, each term points toward the secret powers and philosophies that shaped the Western esoteric tradition.

The work is not a dismissal but an invitation: an attempt to unlock the coded vocabulary of mysticism, to make the hidden sciences speak to those willing to listen. For collectors and practitioners alike, it stands as a rare map of the occult’s secret terrain.
