The core tenets of Daesoon Jinrihoe in Jeungsanism are encapsulated in the teachings of Eumyang-hapdeok (陰陽合德, Virtuous Concordance of Yin and Yang), Shinin-johwa (神人調化, Harmonious Union between Divine Beings and Human Beings), Haewonsangsaeng (解冤相生, Resolution of Grievances for Mutual Beneficence) and Dotongjingyeong (道通眞境, Perfected Unification with Dao). Among them, the first three teachings eventually turn towards the prophetic thought of Dotong-jingyeong, which is the process of man becoming a divine figure. While these principles are considered crucial advice for overcoming an unstable life, there are many curious questions that help for better comprehension. What is the reality of Jin-gyeong (眞境) for their followers? How can one reach the ultimate stage under this belief system? Is this ideological concept different from similar perspectives of other major religions? How is this concept related to the idea of Jisang-cheonguk (地上天國, earthly paradise)? This paper analyses these issues of Jin-gyeong from the historical and social narratives of Haengnok (行錄, Acts), Gongsa (公事, Reordering Works), Gyoun (敎運, Progress of the Order), Gyobeop (敎法, Dharma), Gwonji (權智, Authority and Foreknowledge) and Yesi (豫示, Prophetic Elucidations) in The canonical scripture of Jeon-gyeong and also from the ontological approaches of East Asian faiths in order to identify alternative notions of Daesoon cosmology. The paper, based on the sayings of Kang Jeungsan, particularly his philosophy of the Later World, argues the insight that the Jin-gyeong world can be interpreted as created through the Cheonji-gongsa (天地公事, Reordering Works of Heaven and Earth) project in terms of Gaebyeok (開闢, Great Opening) and the earthly paradise as open only for those who achieve the condition of Sin-ingan (新人間, literally means ‘new humans’ but symbolizing ‘being a human-god’) by the personal cultivation of Dotong (道通, the unity with Dao).
