The heavenly mandate proclaimed through Donghak pointed toward a fulfillment yet to come. That fulfillment arrived in 1871, when Jeung-san Sangjenim—the Ruling God of Heaven and Earth—incarnated as a human being in the Eastern land of Korea. With His advent, the True Eastern Learning, Jeung San Do, came into being.

Sangjenim carried out an unparalleled work of cosmic renewal: rectifying the disordered principles of Heaven and Earth, reforming both the human world and the spirit realm, and transforming the prevailing order of mutual conflict and domination into one of Sangsaeng (相生)—mutual life-giving and cooperation. This was not the work of a sage or reformer, but of the Ruler of Heaven and Earth acting directly within human history.

From 1901 to 1909, Sangjenim conducted the Cheonjigongsa—the Works of Renewing Heaven and Earth—laying the cosmic and historical foundations for the Later Heaven’s fifty-thousand-year civilization. In this new era, humanity will live as one family, united under the order of Sangsaeng, beyond the divisions of nation, race, and creed that defined the Early Heaven.

Central to this great work was the completion of the Taeeulju Mantra—the most sacred and essential practice for humanity to navigate the Gaebyeok of Cosmic Autumn and enter the new world. The Taeeulju was completed by Sangjenim Himself when He came to earth: a gift from the Father of Heaven to all of humanity at the turning point of civilization.

Before His ascension, Jeung-san Sangjenim conferred the Dao lineage and spiritual authority upon a woman, Goh Pan-rye, honored as Taemonim. This was an unprecedented event in the history of the Early Heaven, whose cultures had almost universally placed religious and spiritual authority in male hands. Sangjenim’s act was not merely a personal succession but a cosmic proclamation: that the vertical and hierarchical order of the Early Heaven—in which heaven governed earth, yang dominated yin—would give way in the Later Heaven to a relationship of parallel dignity and complementarity between yin and yang. The entrusting of the Dao lineage to Taemonim embodied this new order before it had yet fully arrived.

Following this transmission, Taemonim founded the first movement to spread and preserve Sangjenim’s teachings, ensuring their continuity across the great threshold of Gaebyeok and into the civilization of the Later Heaven.
