▶️ The Twelve Decision Bodies: Day Master Cognition, Choice Cadence, and the Interiority of Regret
The Twelve Decision Bodies: Day Master Cognition, Choice Cadence, and the Interiority of Regret by Dr. Juan Carlos Rey is a disciplined reexamination of Chinese Day Master theory as a study of decision mechanics rather than personality, fate, or identity.
This book treats choice as an interior process shaped by speed, load, ambiguity, duty, and recovery.
Each of the twelve Day Masters is presented as a distinct decision body, revealing how judgment forms under pressure, how it deforms under excess, and how regret arises when scale, timing, or moral weight exceed constitutional capacity.
Drawing from classical Chinese thought, applied cognitive science, and behavioral psychology, Dr. Juan Carlos Rey replaces typology with diagnostic clarity. Regret is read as a signal rather than a failure. Override replaces fatalism. Agency is preserved without bravado.
Written for clinicians, analysts, strategists, creatives, and serious self-students, The Twelve Decision Bodies offers practical frameworks for decision hygiene, crisis override, workload structuring, financial timing, creative recovery, and ethical boundary setting. Readers learn how to pace commitment, prevent burnout, correct misalignment, and act decisively without self-erasure.
This is not a promise of certainty.
It is a manual for proportion.
For those who think deeply, decide often, and refuse to confuse identity with habit, this work offers restraint, precision, and a rare interior calm.
Choice improves when strain is understood.
▶️ The Argonautica Vault: Apollonius’ Hidden Library
The Argonautica Vault: Apollonius’ Hidden Library is a groundbreaking scholarly work that reinterprets Apollonius Rhodius’ Argonautica as a concealed archive of endangered ancient knowledge. Drawing on Hellenistic poetry, Alexandrian scholarship, ritual studies, and cultural memory theory, the book argues that the Argonautica functions as a mnemonic ark - preserving lost mythologies, ritual practices, genealogies, and esoteric traditions in the aftermath of cultural collapse.
Written for classicists, historians of religion, and interdisciplinary scholars, the book situates Apollonius within the intellectual world of the Library of Alexandria, revealing the influence of Callimachus, Zenodotus, Orphic traditions, and early magical texts such as the Greek Magical Papyri. Special attention is given to Medea as a priestess and living archive of pharmakological and solar cult knowledge, challenging modern reductions of her figure to psychology or tragedy.
Through close textual analysis and disciplined speculative reconstruction, The Argonautica Vault explores ritual geography, initiatory narrative structure, and the ethics of memory preservation in an age of loss. The work combines rigorous philology with imaginative cultural archaeology, offering a new model for reading ancient epic as an instrument of survival rather than conquest.
This book is essential reading for those interested in:
Apollonius Rhodius and the Argonautica
The Library of Alexandria and Hellenistic scholarship
Myth, ritual, and cultural memory in ancient Greece
▶️ The Twelve Constitutional Bodies
The Twelve Constitutional Bodies: Earthly Branches, Elemental Physiology, and Preventative Medicine
This book presents Traditional Chinese Medicine as a disciplined system of constitutional literacy rather than a catalog of symptoms, cures, or beliefs.
Drawing on classical medical theory, Earthly Branch timing, and pattern-based physiology, it reframes health as a matter of rhythm, reserve, and response under load. The twelve Earthly Branches are treated not as symbolic animals or personality types, but as constitutional architectures that reveal where stress accumulates, how compensation unfolds, and which systems fail first when reserve is exhausted.
Each chapter examines one Branch as it manifests across Element and polarity, offering a comparative map of vulnerabilities, imbalance patterns, dietary regulation, physical practices, and herbal logic. Profiles are written for clarity and consistency, allowing readers to track variation without metaphor or moral framing. Nothing here is diagnostic. Nothing is prescriptive. The aim is early recognition, not intervention theater.
Part I provides the constitutional analyses themselves, keyed explicitly to the Earthly Branch of the Day Pillar in the Four Pillars system. This choice reflects a clinical premise: that embodied physiology and stress response are most reliably observed through the Day Branch, with Year, Month, and Hour understood as modifiers of timing and expression rather than core substrate.
Part II serves as a rigorous reference apparatus. It includes a clinical glossary of Traditional Chinese Medicine terms, an herb glossary grounded in classical function and modern safety boundaries, methodological clarifications for practitioners, correction of common mistranslations and semantic errors, and a cross-reference index linking Branches to organ systems, practices, and therapeutic themes. Clear scope boundaries are stated throughout.
This volume is written for practitioners, advanced students, and educated readers who want coherence without mysticism and structure without reduction. It does not promise cures. It does not flatten Chinese medicine into lifestyle advice. It offers something rarer: a way to read the body as a patterned system across time, and to intervene early by respecting pace, reserve, and form.
Health, here, is not optimization. It is intelligent conservation.
▶️ Lotería The Vernacular Art of Fate in Image and Voice
Lotería The Vernacular Art of Fate in Image and Voice
This book does not rescue Lotería from obscurity.
It assumes Lotería never needed rescuing.
Played for centuries at kitchen tables, in courtyards, at festivals, and in moments of waiting, Lotería has endured by doing something rare: it has remained intelligent without demanding to be believed, meaningful without insisting on explanation, and sacred without ever claiming holiness. Treated too often as a child’s game, a nostalgic artifact, or a folkloric curiosity, it has quietly performed a more difficult labor. It has taught people how to meet chance together.
Lotería: The Vernacular Art of Fate in Image and Voice approaches the game as what it has always been: a complete symbolic system disguised as play. Through careful historical inquiry, close attention to images and calls, and an unsentimental examination of performance, rhythm, and communal attention, this work reveals how Lotería organizes memory, meaning, and recognition without doctrine, authority, or canon.
Here, the cards are not decoded. They are listened to.
The calls are not explained. They are heard.
The board is not interpreted. It is encountered.
Drawing from cultural history, performance studies, visual theory, and divination scholarship, the book traces Lotería from its European lottery ancestry through colonial Mexico and into migration, diaspora, and digital dilution. Along the way, it demonstrates why Lotería resisted codification, how humor and double entendre function as moral intelligence, and why the game remains ethically potent precisely because it refuses to command belief or prediction.
This is not a manual.
It is not a mystical system in disguise.
It is not nostalgia with footnotes.
It is a serious study of a popular sacred thing.
For scholars, the book offers a rigorous account of symbolic meaning that operates without hierarchy. For occultists, it presents a bracing challenge to authority-driven divination. For general readers, it restores dignity to a game they may have loved without ever being taught how carefully it was made.
Lotería never asked permission to speak about fate.
This book asks only that we finally listen.
▶️ Twin Vaults of The World: Virgil’s Georgics and Apollonius’ Argonautica
Twin Vaults of The World: Virgil’s Georgics and Apollonius’ Argonautica as Ciphered Epics of Preservation
Twin Vaults of the World is a scholarly and poetic study by Dr. Juan Carlos Rey examining Virgil’s Georgics and Apollonius Rhodius’ Argonautica as deliberate works of cultural preservation written under conditions of instability and historical risk. Rejecting readings that frame these poems as pastoral ornament or heroic imitation, Dr. Rey argues that both texts operate as ciphered archives - poetic vessels engineered to carry endangered knowledge across political upheaval, institutional collapse, and the disappearance of libraries.
Through sustained close reading of meter, structure, ritual cadence, catalogues, and mythic endings, Twin Vaults of the World demonstrates how Apollonius and Virgil embedded geography, genealogy, astronomy, agriculture, pharmacology, and ethical instruction within narrative form. Voyage and labor emerge as parallel mnemonic systems, while deliberate non-closure, loss, and ritual limitation function as safeguards against reduction and misuse.
Written for classicists, historians of religion, students of ancient science, and readers concerned with memory, transmission, and cultural survival, this book reframes epic poetry as custodial labor rather than celebration. Dr. Juan Carlos Rey presents epic as a technology of endurance - verse acting as archive when libraries fail and certainty cannot be assumed.
Ideal for readers of classical literature, Hellenistic poetry, Roman didactic verse, mythology, ritual studies, and the history of knowledge.
▶️ The Atlas of Compatibility
The Atlas of Compatibility: A Guide to Harmonies, Clashes, and the Invisible Architecture of Relationships
The Atlas of Compatibility is a definitive, cross-cultural guide to relationship astrology, compatibility analysis, and symbolic pattern recognition, integrating Chinese BaZi astrology, Day Master theory, and Five Element metaphysics with the interpretive precision of Western Tropical astrology. Authored by Dr. Juan Carlos Rey, this work transforms complex astrological systems into a rigorous, actionable framework for understanding human relationships, emotional dynamics, lineage patterns, and life timing.
Drawing on decades of comparative religious studies, classical scholarship, and applied astrological practice, The Atlas of Compatibility dissolves the artificial divide between Eastern and Western astrology. Instead, it reveals a unified cosmological architecture governed by polarity, elemental interaction, rhythm, and relational reciprocity. Readers learn how Day Masters regulate emotional metabolism, how San He (Three Harmonies) and Liu Chong (Six Clashes) parallel Western harmonic and oppositional aspects, and how cycles of stability, disruption, and transformation shape intimacy, family systems, and vocational alignment.
Designed for both scholars and practitioners, this volume functions simultaneously as an astrology textbook, compatibility manual, symbolic diagnostic system, and working almanac. Each chapter develops practical fluency across key domains: behavioral typology, emotional pacing, conflict repair, intergenerational compatibility, and long-term relational stability. Clear analytical models replace vague intuition, allowing readers to assess relationships with intellectual confidence and clinical clarity.
The appendices provide the technical backbone of the system, including Day Master reference tables, elemental compatibility matrices, and a complete, step-by-step exposition of the classical Five Rats Chasing the Day calculation method. This empowers readers to calculate BaZi charts independently, without reliance on software, apps, or external authorities.
Rigorous, empirical, and deeply humane, The Atlas of Compatibility stands as both a bridge between astrological traditions and a modern toolkit for relational intelligence. It is essential reading for those seeking precision astrology, relationship diagnostics, and a coherent cosmological model through which intimacy, choice, and destiny can be understood with clarity and dignity.
▶️ Action and Strain: A Constitutional Guide to Daily Choice
Action and Strain: A Constitutional Guide to Daily Choice is a rigorous, original work by Dr. Juan Carlos Rey that reframes Chinese Day Master theory as a discipline of decision-making rather than personality, fate, or prediction.
Built to accompany Dr. Rey’s Decision Almanac spanning 1900–2050, this guide teaches readers how actions land on different constitutions under real-world pressure. Instead of asking what will happen, it asks what can be carried cleanly today. The result is a practical framework for reducing regret while preserving agency.
Drawing from classical Chinese process thought, modern cognitive science, stress physiology, and moral psychology, the book introduces action classes, strain signals, override thresholds, and recovery principles that apply to work, contracts, money, health, conflict, creativity, and long-term planning. Timing is treated as descriptive rather than commanding. Choice remains human, embodied, and accountable.
Written for clinicians, analysts, strategists, creatives, and serious self-students, Action and Strain offers tools for pacing decisions, preventing burnout, correcting misalignment, and acting with proportion under load. It rejects fatalism, prediction, and obedience in favor of clarity, restraint, and lived judgment.
This is not a promise of certainty.
It is a manual for carrying choice without damage.
For readers seeking depth without mysticism and structure without coercion, this work stands apart.
▶️ Chance as a Cultural Language: Toward a New Vocabulary of Play, Meaning, and Fate
Chance as a Cultural Language: Toward a New Vocabulary of Play, Meaning, and Fate introduces a rigorous and unsettling proposition: that chance has always spoken fluently, and that modern culture has simply forgotten how to listen.
Rejecting the authority-driven models that dominate contemporary divination, symbolism, and game studies, this book presents Gero as a new analytic vocabulary for understanding how meaning arises through structured chance, shared attention, image, voice, and repetition. Gero does not function as a belief system, a method, or a predictive tool. It names a cultural condition in which fate is encountered without obedience, interpretation occurs without hierarchy, and meaning circulates without ownership.
Drawing on cultural history, performance theory, visual studies, anthropology, and the study of play, the book examines how societies have long used games, lots, images, and communal ritual to negotiate uncertainty. From lotteries and vernacular games to informal divination practices and popular sacred forms, Chance as a Cultural Language demonstrates that symbolic intelligence often survives most clearly where it is least institutionalized.
Central to the work is a sustained critique of interpretive authority. Tarot orthodoxy, occult professionalism, and rigid symbolic systems are examined not to be dismissed, but to be contrasted with practices that refuse codification and mastery. In their place, the book offers a disciplined account of how meaning can emerge through play without collapsing into superstition or control.
This is not a manual.
It is not a system.
It is not a defense of randomness.
It is a serious, erudite exploration of how humans make sense together when certainty is unavailable and belief is optional.
For scholars of religion, anthropology, game studies, and cultural theory, the book provides a precise language for analyzing non-doctrinal symbolic systems. For occult practitioners, it offers a direct challenge to inherited assumptions about authority and interpretation. For general readers, it reframes play, chance, and fate as culturally literate practices rather than distractions or mysteries.
Chance as a Cultural Language argues that fate does not need interpreters, only conditions under which it can be noticed.
Gero names those conditions.
And once named, they become impossible to ignore.
▶️ A Very Brief History of Spirit Communication
A Very Brief History of Spirit
Communication offers a concise yet richly scholarly exploration of one of humanity’s most enduring pursuits: communion with the unseen. From ancient temples to modern séances, this volume traces the global history of spirit communication as a serious religious, cultural, and psychological phenomenon.
Authored by Dr. Juan Carlos Rey, a scholar of comparative religion and esoteric traditions, the book examines spirit communication across civilizations, including Ancient Egypt, Mesopotamia, Greece and Rome, Indigenous American shamanism, African and Afro-Caribbean traditions, Asian spirit-medium lineages, Victorian Spiritualism, and contemporary New Age channeling.
Rather than reducing mediumship, trance, or possession to superstition, this work approaches spirit communication through historical documentation, anthropological context, and symbolic analysis. Readers encounter the akh of Egypt, the oracles of Delphi, Afro-Caribbean possession rites, Siberian and Mongolian shamanism, liver divination, séance culture, and modern metaphysical movements as part of a continuous human dialogue with the invisible.
Clear, structured, and academically grounded, A Very Brief History of Spirit Communication is ideal for students of religion, spiritual practitioners, historians, psychologists, and curious readers seeking an informed understanding of how cultures have interpreted contact with spirits, ancestors, gods, and non-ordinary realities.
As long as humanity seeks guidance, meaning, and connection beyond the visible world, spirit communication remains a vital expression of our shared symbolic inheritance.
▶️ The Cast of Ages: Dice, Divination, and Destiny in the Ancient World
The Cast of Ages: Dice, Divination, and Destiny in the Ancient World
The Cast of Ages is a sweeping, interdisciplinary study of dice as humanity’s oldest and most enduring instruments for interpreting fate, chance, and meaning. Blending archaeology, comparative religion, anthropology, philosophy of probability, and divination studies, Dr. Juan Carlos Rey traces the cultural and symbolic history of dice from their earliest appearances in Mesopotamian omen traditions to Egyptian ritual contexts, Greek astragalomancy, Roman gaming and augury, and the divinatory practices of Africa, Asia, and the ancient Mediterranean world.
Far beyond a history of games or gambling, this volume positions dice as sacred technologies of uncertainty - material tools through which civilizations explored cosmic order, agency, randomness, and the tension between fate and free will. Dr. Rey demonstrates how dice functioned simultaneously as ritual objects, philosophical provocations, and symbolic mirrors of the human psyche, long before the emergence of modern statistics or probability theory.
Integrating classical sources, material culture, and contemporary cognitive theory, The Cast of Ages reveals a continuous lineage between ancient divination systems and modern mathematical, psychological, and scientific approaches to chance. The book illuminates how cultures encoded metaphysical meaning into randomness, and how the simple act of casting a die shaped religious ritual, ethical reasoning, and the evolution of symbolic thought across more than five thousand years.
Written with academic rigor, lyrical clarity, and a distinctly interdisciplinary voice, The Cast of Ages is essential reading for scholars of religion, mythology, divination, cultural history, and esoteric studies, as well as for readers fascinated by the deeper structures underlying probability, uncertainty, and belief. This work stands as a definitive exploration of how humanity has long sought wisdom not despite randomness, but through it.
▶️ The Grammar of Fate: An Academic and Esoteric Guide to Numerology
The Grammar of Fate: An Academic and Esoteric Guide to Numerology
The Grammar of Fate presents a comprehensive, multi-traditional exploration of numerology, one of humanity’s oldest and most enduring symbolic sciences. Drawing upon traditions spanning the ancient Near East, classical Greece and Rome, Kabbalistic Judaism, Vedic India, Chinese metaphysics, African cosmology, and diasporic ritual systems, it offers a unified and scholarly account of how number has been used to describe personality, guide destiny, interpret cycles of time, and reveal the deeper architecture of the cosmos.
Rather than treating numerology as a single doctrine or isolated technique, this volume examines it as a constellation of interrelated philosophical systems, shaped by shared intuitions about order, harmony, rhythm, and meaning. Across cultures, number emerges not merely as a tool of calculation, but as a symbolic language capable of articulating identity, fate, transformation, and cosmic law.
Beginning with the foundations of numerical symbolism, reduction methods, and vibrational theory, the book proceeds through the major Western, Eastern, and African numerological traditions with clarity and academic precision. It offers in-depth analysis of Pythagorean, Chaldean, Kabbalistic, Vedic, Chinese, Tamil, and Yoruba-based numerology, demonstrating both their distinctive methodologies and their underlying coherence. Readers are shown how different cultures encoded psychological insight, cosmological structure, and ritual timing through number.
The later chapters provide practical instruction in core numerological techniques, including Life Path analysis, Destiny and Soul Numbers, compound number interpretation, name vibration, forecasting, and cyclical timing systems. These methods are supported by fully developed sample readings and case studies, illustrating how numerical patterns function in real-world divinatory and diagnostic practice. The book then moves beyond technique into integrative territory, exploring how numerology intersects with personality theory, symbolic psychology, ritual structure, astrology, and divinatory decision-making.
Extensive appendices supply essential reference materials, including conversion tables, compound number meanings, sample chart structures, cross-cultural correlation systems, and an extended treatment of the Luoshu Square as used in Chinese numerology. Together, these resources form a complete toolkit for beginners, advanced practitioners, and scholars engaged in the comparative study of symbolic systems.
Throughout, the work maintains an erudite yet accessible tone, treating numerology as a serious intellectual and philosophical tradition rather than a novelty or superstition. It situates number within philosophy, cosmology, cultural history, and metaphysics, arguing that numerical symbolism reflects a universal human attempt to understand the structure of existence itself.
Whether approached as a divinatory method, a philosophical lens, a psychological framework, or a ritual technology, numerology reveals the patterns that shape personal destiny and collective experience. This book is an invitation to read the world through number – to perceive the hidden order beneath events, the rhythms within time, and the narrative of identity written in the digits that accompany every life.
