Book 1 was updated to a second edition and released on April 8, 2025. If you bought it before, contact the author via Facebook or Instagram for a free e-book. This newly updated Second Edition of Daoist Cultivation, Book 1: Fundamental Theory and Philosophy offers a significantly refined and enriched reading experience. While the number of pages remains approximately the same, the content has been carefully restructured and expanded — many original illustrations were removed to create space for substantial new material and a more focused, in-depth presentation. What’s New and Improved: -- Expanded Depth: Core principles such as the Three Treasures (Jing, Qi, Shen), the Three Dantian, and the Central Channel (Zhong Mai) are now explained with greater clarity and structure, guiding the reader through each stage of internal transformation. -- Classical Sources: Original teachings and symbolism from classical Daoist texts — including the Xiuzhen Tu and Taijitu Shuo — are now fully integrated into the theoretical framework, showing their relevance to internal cultivation. -- New Content: Entirely new chapters have been added, such as Levels of External Qi, Ling Qi, Hunran Yi Qi, and a revised and expanded presentation of Daoist Cosmology, connecting Neidan practice with cosmological unfolding. -- Terminological Clarity: Terms such as Yuan Qi, Ling Qi, Zhen Qi, Zheng Qi, and Hunran Yi Qi are now clearly defined and contextualized. Key distinctions — such as between Pre-Heaven and Post-Heaven energies, or between Yuan Qi and Ling Qi — are clearly defined, with consistent Chinese terminology used throughout. -- Visual and Conceptual Refinement: Though some illustrations were removed, new flowcharts, tables, and symbolic diagrams have been added to help readers internalize the structure and logic of Daoist theory. Despite these additions, the book remains accessible to all levels — whether you are just entering the Daoist path or seeking a deeper framework to support your cultivation. This second edition presents a clearer, more mature articulation of the foundations of Daoist internal practice and serves as a practical companion to the unfolding series. This book also provides detailed explanations of essential terms such as Qigong, Neigong, Neidan, Jing–Qi–Shen, Wu Xing, Ming Gong, and Xing Gong, making it an ideal resource for both beginners and experienced practitioners. It presents the principles of Yin–Yang and Wu Xing (Five Phases) with a traditional lens, restoring the deeper meaning often omitted or misunderstood in modern interpretations. Special attention is given to key topics such as: -- "The Gate of All Marvelous-Mysterious" — a vital inner state required for returning to the Primordial -- "Centers and Channels" — a practical explanation of the Dantians, energy system, and meridians, including visual diagrams of the 12 primary and 8 extraordinary channels -- "Building the Foundation", "Body Foundation", "Heart-Mind Foundation", and "Virtue Cultivation" — core stages for beginning the Daoist path This book is highly recommended for anyone interested in traditional Daoist methods of self-development, as well as those practicing Qigong, Neigong, Neidan, or Taiji (Taichi).
