A Living Tradition of the Americas
In the autumn of 1900, a sixteen-year-old musician in Fairport, New York, was practicing the piano when a voice spoke to him. It said: "Will you write a book about the true nature of the Tarot?" The boy was Paul Foster Case, and he did not know what the Tarot was. He would spend the next fifty-four years answering the question.
Case became, by almost universal acknowledgment among practitioners of the Western esoteric tradition, the finest English-language interpreter of the Tarot and the Qabalah in the twentieth century. His B.O.T.A. Tarot deck — deliberately austere, black-and-white, designed to be colored by the student as a meditative practice — is the most widely used occult teaching deck in the world. His books on the Tarot (particularly The Tarot: A Key to the Wisdom of the Ages*) and on the Qabalah (particularly* The True and Invisible Rosicrucian Order*) have been in continuous print since the 1930s. His organization — Builders of the Adytum — has operated without interruption since 1922, quietly training students in the Western mysteries through a correspondence course that arrives, week by week, as a lesson in the mail.*
B.O.T.A. is not a church, not a secret society in the conspiratorial sense, and not a magical order in the dramatic sense. It is a school — a disciplined, systematic, graded program of study in the Qabalah, the Tarot, and the practical application of the Western esoteric tradition to the development of consciousness. Its "adytum" is the innermost sanctuary of the ancient temple — the holy of holies — and B.O.T.A.'s proposition is that this sanctuary exists not in a building but in the human mind. The work of the builder is to construct it.
I. The Name and the Tradition
Builders of the Adytum — the name is drawn from the Greek adyton (ἄδυτον), the innermost chamber of an ancient temple, accessible only to priests. In esoteric usage, the adytum represents the innermost sanctuary of consciousness — the divine presence within the human mind. The "builders" are the students and practitioners who, through disciplined study and meditation, construct this inner temple.
The tradition B.O.T.A. transmits is the Western mystery tradition — the stream of esoteric philosophy and practice that runs from Hermetic Egypt through Neoplatonism, through Jewish Kabbalah, through the Rosicrucian manifestos of the seventeenth century, through Freemasonry, through the Hermetic Order of the Golden Dawn, to the present. This is not a single lineage but a river with many tributaries, united by a common set of tools: the Qabalah (specifically the Tree of Life as a map of consciousness), the Tarot (as a pictorial encyclopedia of the tradition's principles), and ceremonial practice (ritual, meditation, and invocation as methods of spiritual development).
B.O.T.A. is directly descended from the Hermetic Order of the Golden Dawn — the late-Victorian magical order that, in its brief heyday (1888–1903), produced an extraordinary synthesis of Qabalah, Tarot, astrology, alchemy, and ceremonial magic that has defined the Western esoteric tradition ever since. Case received the Golden Dawn current through Alpha et Omega (the continuation of the original Golden Dawn under S.L. MacGregor Mathers and then J.W. Brodie-Innes) and, more importantly, through his own direct study and inner experience.
II. Paul Foster Case — The Founder
Paul Foster Case (1884–1954) was born in Fairport, New York, a small town near Rochester. His father was the librarian of the Fairport public library, and Case grew up surrounded by books. He was musically gifted and worked as a professional musician — an organist and pianist — throughout his early career. His interest in the Tarot, initiated by the mysterious voice he heard at sixteen, led him into an intensive study of occult literature.
In 1909, Case published his first article on the Tarot. In 1910, he met Claude Bragdon, the architect, writer, and Theosophist who introduced him to the wider world of American esotericism. In the mid-1910s, Case was initiated into Alpha et Omega, the successor body of the Golden Dawn, through Michael Whitty's Thoth-Hermes Temple in Chicago. He rose rapidly through the grades, demonstrating an unusual combination of intellectual precision and meditative depth.
By 1920, Case had achieved the highest grades available in the Alpha et Omega system and had been appointed Praemonstrator (chief of instruction). A dispute with Moina Mathers (MacGregor Mathers' widow, who controlled the Alpha et Omega) over the inclusion of sexual magic in the curriculum led to Case's departure in 1921–1922. Moina wished to incorporate the sexual teachings of the Ordo Templi Orientis (O.T.O.); Case disagreed, holding that the Western mysteries as transmitted through the Golden Dawn were complete without them and that the introduction of sexual techniques would distort the tradition.
In 1922, Case founded Builders of the Adytum as an independent school, initially based in Boston and later (from 1932) in Los Angeles. He spent the remaining thirty-two years of his life developing the curriculum, writing the lessons, producing the B.O.T.A. Tarot deck, and training students through the correspondence method.
Case died on March 2, 1954, in Acapulco, Mexico, while on vacation. Leadership passed to his most trusted student, Ann Davies (1912–1975), who expanded the School's international reach and deepened its teachings, particularly in the area of meditation and the practical application of Qabalistic principles.
After Davies' death, the School has been led by successive Prolocutors General, maintaining the curriculum and organizational structure Case established.
III. The Qabalah — The Master Diagram
B.O.T.A.'s Qabalah is the Hermetic Qabalah — the Western esoteric adaptation of Jewish Kabbalah, developed through the Renaissance Christian Cabala (Pico della Mirandola, Reuchlin, Agrippa), the Rosicrucian tradition, and the Golden Dawn. It differs from traditional Jewish Kabbalah in several respects: it incorporates Tarot correspondences, astrological assignments, and alchemical symbolism into the Tree of Life, and it treats the Qabalah as a universal map of consciousness rather than as a specifically Jewish mystical path.
The Tree of Life (Etz Chaim) is the central diagram: ten spheres (sephiroth) connected by twenty-two paths, representing the emanation of consciousness from the infinite (Ain Soph) through successive levels of manifestation to the physical world. Each sephirah corresponds to a level of consciousness, a divine name, an archangel, an angelic order, a planetary or zodiacal attribution, and (in B.O.T.A.'s system) a specific color, musical tone, and meditation practice.
The twenty-two paths connecting the sephiroth correspond to the twenty-two letters of the Hebrew alphabet and, in the Golden Dawn / B.O.T.A. system, to the twenty-two Major Arcana of the Tarot. This correspondence — each path = one Hebrew letter = one Tarot trump — is the structural principle that unifies the Qabalah and the Tarot into a single system.
B.O.T.A.'s curriculum teaches the Tree of Life not as an abstract cosmological diagram but as a practical map for meditation. Each sephirah and path is explored through study, visualisation, and the coloring of the corresponding Tarot key. The process of working through the Tree, from Malkuth (the material world) to Kether (the crown, the highest consciousness), is understood as the process of spiritual development itself.
IV. The Tarot — A Pictorial Textbook
Case's interpretation of the Tarot is B.O.T.A.'s most widely known contribution. His core claim: the Tarot is not a fortune-telling device but a pictorial textbook of ageless wisdom. The twenty-two Major Arcana (the Fool through the World) are not arbitrary images but a precise visual encoding of the principles of the Western mystery tradition — each card corresponds to a Hebrew letter, a path on the Tree of Life, an astrological sign or planet, and a specific principle of consciousness.
The B.O.T.A. Tarot deck, designed by Case and drawn by Jessie Burns Parke, is deliberately presented in black-and-white outline. Students are instructed to color the cards themselves, following precise color instructions based on the Qabalistic color scales. The act of coloring is itself a meditative practice: by carefully applying the correct colors to the symbolic elements of each card, the student internalises the card's teaching at a level deeper than intellectual study alone can reach. Case called this "painting the paths" — and the practice has no equivalent in any other Tarot tradition.
Case's Tarot follows the Golden Dawn's attributions (which differ from the earlier French occult tradition's attributions in significant ways — notably in assigning the Fool to Aleph and the path between Kether and Chokmah, rather than to the penultimate position). His interpretations of individual cards, published in The Tarot: A Key to the Wisdom of the Ages (1947), are distinguished by their intellectual precision, their psychological depth, and their integration of Qabalistic, astrological, and alchemical symbolism into a coherent whole.
V. The Curriculum and Method
B.O.T.A. operates as a correspondence school. Students apply for membership, receive a series of weekly lessons by mail (now also available digitally), and work through a graded curriculum that covers:
- The Seven Steps — an introductory course on the basic principles of the Western mystery tradition.
- The Tarot Fundamentals — a detailed study of all twenty-two Major Arcana, including the coloring practice.
- The Tarot Interpretation — the Minor Arcana and Court Cards, their Qabalistic attributions, and their use in meditation and self-understanding.
- Qabalistic Fundamentals — the Tree of Life, the sephiroth, the Hebrew letters, the divine names.
- Advanced courses — covering spiritual alchemy, the Cube of Space (a three-dimensional arrangement of the Hebrew letters), sound and color as tools of consciousness, and ceremonial practice.
The method is disciplined and cumulative: each week's lesson builds on the previous, and students are expected to practice the meditations, color the cards, and study the material before advancing. There is no fast track. The curriculum takes years to complete.
B.O.T.A. maintains pronaoi (study groups) in cities around the world, where members meet to practice group meditations, discuss the lessons, and participate in ceremonial rituals. The pronaoi provide the communal dimension that the correspondence method lacks — a way for solitary students to practice in a group context.
VI. The Western Mysteries and B.O.T.A.'s Place
B.O.T.A. occupies a specific niche in the landscape of Western esotericism. It is:
More disciplined than most Golden Dawn descendants. Where many post-Golden Dawn groups devolved into personality conflicts, schisms, and dramatic claims to occult authority, B.O.T.A. maintained Case's emphasis on quiet, systematic study and practice. The School does not claim spectacular occult powers, does not promote its leaders as adepts, and does not engage in the competitive one-upmanship that has characterised much of the Golden Dawn legacy.
More intellectually rigorous than most New Age alternatives. B.O.T.A.'s curriculum requires sustained intellectual engagement with the Qabalah, Hebrew, astrology, and the history of Western esotericism. It does not simplify, does not offer shortcuts, and does not promise easy results. The teaching is that genuine spiritual development is the work of a lifetime, and that there are no substitutes for disciplined practice.
More conservative than Thelema. Case explicitly rejected the sexual magic of Aleister Crowley and the O.T.O., and B.O.T.A.'s ethical framework is broadly compatible with conventional morality. The School teaches that the Western mysteries are a path of service and self-development, not of transgression or antinomianism.
More accessible than traditional Freemasonry. B.O.T.A. admits women (unlike most Masonic lodges), does not require belief in a specific deity, and transmits its teachings openly through published books and correspondence lessons rather than through initiatory secrecy alone. Case believed that the esoteric truths encoded in the mystery tradition belonged to humanity and should be made available to serious students of any background.
VII. Current State
Builders of the Adytum continues to operate from its headquarters in Los Angeles (the B.O.T.A. Temple on North Figueroa Street, a building Case and his students constructed). It maintains pronaoi in major cities across the United States, Canada, Europe, Latin America, New Zealand, and Australia. Membership numbers are not published, but the School is estimated to have several thousand active students worldwide.
The B.O.T.A. Tarot remains one of the best-selling esoteric Tarot decks in the world. Case's books remain in print. The correspondence lessons continue to arrive, week by week, in the mailboxes (and now the inboxes) of students who are doing the same work that Case began in 1922: studying the Hebrew letters, coloring the Tarot keys, meditating on the Tree of Life, and building, slowly and systematically, the inner temple that the tradition calls the adytum.
Colophon
Builders of the Adytum was founded in 1922 by Paul Foster Case as a school of the Western mystery tradition, rooted in the Hermetic Qabalah and the Tarot as transmitted through the Golden Dawn lineage. This profile draws on Case's own published works (The Tarot: A Key to the Wisdom of the Ages, 1947; The True and Invisible Rosicrucian Order, 1927), the historical scholarship of Mary K. Greer (Women of the Golden Dawn, 1995), and the published materials of B.O.T.A.'s correspondence curriculum.
