《上清無英真童合遊內變玉經》

This scripture describes the profound realm of the "Wuying Zhen Tong" (True Child of Formless Radiance) in the cultivation methods of the Shangqing (Highest Clarity) school, a major Daoist tradition. It begins by mentioning three scriptures combined into one scroll, with the Shangqing Wuying Zhen Tong Heyou Neibian Yu Jing (Jade Scripture of the Inner Transformation Through Union with the True Child of Formless Radiance) serving as the primary text.

The text depicts the wondrous scene of the Daoist deity Yu Bao Wang Qing Tong Daojun (Jade Guardian King, Green Lad Dao Lord) cultivating in the Floating Azure Cinnabar Grove, a celestial realm. Suddenly, the nine-layered heavenly gates of the Sun Palace, located myriad miles away, open wide, intertwining cinnabar light and purple mists. The Five Thearchs (directional deities) clap in celebration, while the divine bird (the golden crow symbolizing the sun) sings. When the practitioner focuses their gaze with deep concentration, they resonate with the essence of heaven and earth, attaining the harmonious state of "spontaneous generation of Great Harmony."

Next, a celestial being adorned with the moon and stars appears, revealing to Daojun Qing Tong: by attuning to the essence of the sun and moon, one can nurture "Tianying" (Heavenly Radiance, the primordial Qi) within the Dantian (energy center), causing jade mushrooms and immortal herbs to grow naturally within the body. Here, "Wuying" symbolizes the nascent qi of green yang at the dawn of life, while "Zhen Tong" refers to the spiritual entity transformed from primordial essence.

The scripture elaborates on key cultivation principles:

1. The movement of bodily essence (Jing) and Qi: The essence of Water gives rise to will, the essence of Earth generates consciousness, and these ultimately coalesce into bones. The refined essence of bones ascends to nourish the eyes. The eyes are called the "Mystic Window," serving as the gateway to divine connection.

2. Cultivation methods: One must attune to specific celestial hours. When sensing the presence of a spiritual entity (the descent of Wuying) in a part of the body, the practitioner should face the sun and pay homage. Closing the eyes to gaze inward, they will first perceive a red mass of Qi, followed by wheel-like patterns of swirling flowers—a sign of the transformation of essence and Qi.

The core technique lies in Cunsi (visualization and mental retention), where focused contemplation of the form of Wuying Zhen Tong enables "union and shared transformation" with it, ultimately leading to the sublime state where form and spirit are perfected. The text emphasizes that such resonance must follow precise ritual protocols and should never be attempted recklessly.

This scripture describes a Daoist Neidan (internal alchemy) cultivation method, focusing on how to unite with the "True Child of Wuying" (an internal deity) through breath guidance and visualization. The practice unfolds as follows:

Begin by inhaling through the nose, allowing the Qi (vital energy) to descend from the back of the neck along the spine, passing through the kidneys down to the heels before returning to the Dantian (energy center in the lower abdomen). At this stage, one will observe luminous colors manifesting in the Dantian. Silently recite the incantation: "Through spiritual focus, I summon true Qi; inner and outer merge as sunlight blends with flowing mist. Old marrow is cleansed, vitality renewed—the pure Yang energy of Wuying sprouts like tender shoots. Dark influences scatter while lunar and solar radiance nourish this sacred form, aiding my ascent as an immortal official of the higher realms."

During specific monthly hours, practice solitary reclining meditation with focused observation. Each body part corresponds to seasonal nodes: the left foot aligns with the Beginning of Spring (Wuyin and Jichou days), the left chest with the Spring Equinox (Yimao day), the left hand with the Beginning of Summer (Wuchen and Jisi days), the throat and head with the Summer Solstice (Bingwu day), the right hand with the Beginning of Autumn (Wushen and Jiwei days), the right chest with the Autumn Equinox (Xinyou day), the right foot with the Beginning of Winter (Wuxu and Jihai days), and the waist/hips with the Winter Solstice (Renzi day). During these designated periods, guide Qi back to the Dantian and observe the resulting phenomena.

After prolonged practice, floating lights will appear during seated meditation. Continued cultivation reveals the form of the "True Child of Wuying" within these radiances, mirrored by corresponding manifestations in the Dantian. This advanced method was originally transmitted exclusively to perfected adepts of the Shangqing (Highest Clarity) tradition, having been disseminated from the Eastern Florescence Jade Palace by the Daoist immortal Qingtong (Azure Lad), with the Eastern Florescence Guardian of Dawn—the Mysterious Yellow Daoist Lord—imparting it to serious practitioners.

Note: "Wuying" represents one of the internal deities in Daoist cultivation, symbolizing the body's pure Yang energy. The "Dantian," located three finger-widths below the navel, serves as the vital reservoir of Jing (essence) in Daoist practice.
