This is a preface and excerpts from the Lingbao Essential Teachings, a foundational text of the Zhong-Lü alchemical school within Daoism. Authored by Zhongli Quan and transmitted to Lü Dongbin, it details alchemical principles, cosmology, and self-cultivation practices aimed at achieving immortality. The text draws on a compilation of earlier works, emphasizing the interplay of Yin and Yang, the importance of timing, and the refinement of internal energies. Its influence extended to later Daoist schools, solidifying its importance in the history of internal alchemy (Neidan). The preface highlights the author's discovery of the source material and his decision to share this knowledge widely.

This Chapter details a Daoist method for spiritual transcendence, outlining a process of shedding the mortal form to become an immortal being. The text emphasizes internal observation and the cultivation of Qi to achieve this state, describing the stages of spiritual ascent and the visions experienced during this journey. It also provides cautionary advice, highlighting potential pitfalls and the importance of thorough preparation. The ultimate goal is achieving harmony with Heaven and Earth, potentially attaining sainthood and residing in divine realms. Several canonical Daoist texts are cited to support the described practices.

This Chapter from a Daoist text, "Chapter 9 Internal Observation and Exchange," detailing practices for spiritual cultivation. It describes achieving union of heart and Qi through internal observation, employing metaphors to illustrate the formless Dao. The text outlines a specific meditative practice involving visualization and techniques to overcome obstacles, emphasizing the importance of detachment from visions and the pursuit of transcendence beyond physical limitations to achieve true immortality. Ultimately, it stresses simplification and transcendence of methods as the path to ultimate truth.

This Chapter from a Taoist alchemical manual, detailing a system of Qi refinement ("Morning Ascension and Qi Refinement"). It describes the correspondence between the five elements, numbers, directions, and colors, relating these to internal organs and seasonal practices. The text outlines a regimen involving internal visualization, breathwork, and meditative practices to cultivate and ascend Qi. The ultimate goal is spiritual transcendence and sainthood, indicated by physical and spiritual manifestations such as radiant Qi and enhanced perception. Success hinges on disciplined practice and avoidance of distractions.

This Chapter details a Taoist alchemical practice called "Golden Liquid Returning the Elixir" and "Refining the Form." It describes the process of manipulating internal energies, visualized as the interplay of sun and moon, heart and kidney Qi, and gold and jade liquids, to achieve physical and spiritual transformation. The practice involves specific breathing techniques, visualizations, and seasonal adjustments, aiming to achieve immortality through the refinement of the body's energies. The text includes instructions, invocations, and descriptions of expected physical and spiritual changes. Ultimately, mastery of this practice promises enhanced vitality, enlightenment, and a state of harmony with the Dao.

This Chapter details a Taoist alchemical practice, "Jade Liquid Returning the Elixir," aiming for physical and spiritual transformation. The process involves a 300-day regimen of internal alchemy, focusing on cultivating and refining Qi ("vital energy") through specific techniques like saliva manipulation and breathwork. Analogies to natural processes, such as the formation of gold and jade, illustrate the transformation sought. The practice culminates in the "Golden Liquid Returning the Elixir," leading to extended life, heightened senses, and the ability to heal others. Seasonal variations and specific trigrams (from the Bagua) guide the practice's timing and techniques.

This Chapter details a Daoist internal alchemy practice called "Flying Golden Essence from the Elbows," aiming for immortality. The practice involves aligning bodily energy with cosmic cycles—the Sun and Moon's movements—over 300 days, divided into three phases. It uses visualizations and specific postures to cultivate internal energy ("Qi") and create an "internal elixir." Success is marked by improved health, vitality, and longevity, reflecting a harmony between the microcosm (human body) and macrocosm (universe). The text provides detailed instructions, timing guidelines, and metaphorical explanations rooted in Daoist cosmology and numerology.

This Chapter details an alchemical process for achieving immortality. It describes the interplay of Yin and Yang energies within the body, mirroring cosmic cycles, and outlines a regimen of internal energy refinement through specific practices and seasonal timing. The process involves the symbolic union of internal energies, likened to a pregnancy, culminating in the creation of a "Golden Elixir." Success depends on precise timing, inner harmony, and dedicated practice over many years. The text provides analogies and instructions for practitioners at various stages of advancement.

This Chapter details an alchemical process for achieving spiritual transcendence. It describes the cyclical interplay of Yin and Yang, both cosmically and within the human body, using analogies to explain how to cultivate internal energy. The goal is to unite opposing forces ("True Dragon" and "True Tiger") within the practitioner, resulting in the creation of a "True Embryo" and ultimately, immortality. Specific instructions and visualizations are provided to guide this internal alchemical transformation.

This Chapter explores the cyclical interplay of Yin and Yang, mirroring celestial and human physiological processes. It explains how these forces, represented by water and fire respectively, govern natural order and human health. The text uses analogies of Heaven and Earth, the heart and kidneys, and the solstices and equinoxes to illustrate the dynamic balance between these opposing forces. Practical techniques, such as specific exercises and mindful practices, are offered to harmonize Yin and Yang within the body, thereby cultivating health and longevity. The ultimate goal is to align oneself with the Dao's natural rhythm.
