《太上開明天地本真經》

This passage elucidates the fundamental nature of the Dao and the progression of human civilization, which can be understood through several key aspects:

First, it addresses the essence of the Great Dao. The Dao represents "original truth" (ben zhen) - the fundamental reality, with truth being its core principle, while scriptures serve as vessels conveying this truth. The operation of heaven and earth is rooted in maintaining true illumination (zhen ming) through their cyclical ascents and descents, while the cultivation of sages lies in returning to true spirituality (zhen ling).

Next, it describes cosmic creation and human civilization's development. Since the separation of heaven and earth, the movements of sun and moon (Yin-Yang) established seasonal changes, manifesting light and darkness, with the Three Luminaries (sun, moon, stars) nurturing all things. The virtue of the Three Great Sages (possibly referring to the Three Sovereigns) embodied the creative functions of the Two Modes (Yin-Yang), establishing cosmic order through celestial observation and geographical demarcation, creating writing systems and instituting social structures.

The text then enumerates specific advancements in human civilization: knotting ropes for record-keeping initiated governance systems, drilling wood for fire transformed dietary practices, identifying medicinal herbs for healing, teaching agriculture for sustenance, making clothing for protection, inventing tools to meet needs, constructing shelters from wind and rain, and building boats to cross rivers.

Regarding moral cultivation, it states that preserving one's simple nature leads to longevity, while adhering to fundamental truths brings enlightenment. However, subsequent problems emerged: wisdom became weaponized in conflicts, the Warring States period's indulgence in sensual pleasures caused moral decay, people lost their original nature, violated cosmic principles, creating worldly chaos and ethical collapse that shortened lifespans and brought societal disorder - necessitating penal systems to maintain order.

Finally, it discusses the rise of the Three Teachings (Confucianism, Buddhism, Daoism). Ancient sages established these three pedagogical systems to enlighten humanity, reinterpreting the true Dao. Confucianism emulates heaven-earth's vigorous dynamism (qian kun), applies Yin-Yang principles, follows cosmic righteousness, formulates filial piety and rituals, maintains fundamental truths, practices the Five Constants (benevolence, righteousness, propriety, wisdom, faithfulness) and Four Virtues, comprehends life-death principles, and pursues harmonious moderation. Daoism apprehends heaven-earth's marvelous functions, masters water-fire dynamics, harmonizes sun-moon hun-po (cultivation terms for Yin-Yang energies), achieving balanced restoration of internal-external Yin-Yang to return to one's original nature (fu ming).

This scripture elucidates the fundamental methods for attaining the Dao through cultivation, with its essence lying in returning to the origin and stabilizing the foundation. Here is the modern interpretation:

Cultivation should be like a great tree deepening its roots (metaphor for stabilizing the foundation). Through the skillful regulation of Yin-Yang within the body (the "fire phases" refer to energy modulation during practice), one ultimately refines the Golden Elixir (Neidan terminology, denoting the vital essence cultivated through practice), achieving longevity akin to heaven and earth. Those who truly attain the Dao may see their physical form perish, but their spirit (Shen) endures eternally. The key lies in preserving one's innate authenticity (original nature), thereby transcending life and death to unite with heaven and earth.

The text compares the fundamental principles of Confucianism, Buddhism, and Daoism: Confucianism emphasizes human relationships as the foundation to harmonize with the virtue (De) of heaven and earth; Daoism comprehends the transformations of creation through the method of "nurturing warmth" (a Neidan practice technique); while Buddhism advocates realizing the mind's true nature to transcend the constraints of heaven and earth. However, deviations have emerged in contemporary cultivation across these traditions: some discuss fundamentals idly while indulging in desires; others rigidly adhere to doctrines without understanding genuine practice; still others vainly seek Buddhahood without substantive cultivation.

The scripture particularly highlights several crucial aspects of practice: one must study authentic scriptures (Jing), return to the origin, cultivate both body and mind, and maintain spiritual clarity (lucid awareness). Without these, one cannot truly perceive one's nature, penetrate profound mysteries, much less transcend the ordinary to attain sagehood. Finally, it emphasizes that the great matter of life and death transcends sectarian divisions—practice must be grounded in daily life: understanding where the original mind comes from, how true nature manifests, and where it ultimately returns. Only through complete awakening to these fundamental questions can genuine liberation be attained.

This scripture expounds the fundamental principles of cultivation and realization. Titled The Supreme Scripture of Opening Wisdom to Reveal the True Nature of Heaven and Earth, "Supreme" (Taishang) refers to the highest and most transcendent Dao, while "Opening Wisdom" signifies the awakening of true understanding.

The core teaching reveals that those who truly comprehend the Great Dao (Da Dao) neither become immortals nor buddhas—they completely transcend such conceptual distinctions and immediately penetrate the realm of sages across time. Here, the emphasis lies on a fundamental awakening that surpasses religious forms.

The scripture exhorts all people—whether Confucian, Buddhist, or Daoist practitioners, or ordinary virtuous individuals—that by reciting and practicing this classic, they may swiftly attain penetrating wisdom. Through diligent cultivation and genuine comprehension of its profound meaning, one may realize the state of "non-birth" (a Buddhist term denoting transcendence of the cycle of life and death). This awakening far surpasses the teachings of other external paths, even exceeding Buddhism’s "entire canon" (referring to the complete collection of Buddhist scriptures).

It particularly clarifies: The true essential teachings of the scripture are not found in written words, nor within the workings of the mind. The root of attaining the true scripture does not lie in the textual classic itself. One must understand that the key to the Dao’s true scripture lies in oral transmission from heart to heart (direct master-disciple transmission), received with reverence in secrecy and joyfully practiced.

The concluding phrase "joyfully uphold and practice" is a common Buddhist expression, signifying the delighted acceptance and application of the true teachings after hearing them. The entire scripture emphasizes cultivation essentials that transcend form and directly point to the original mind.
