After earning a Master's Degree in political science at a top-notch university in S. Korea, she worked as a college instructor and as a senior level secretary to a congressman and a ranking government official. She also received numerous awards and success as a radio drama writer for the Korea Broadcasting Company. But at the age of 38 she left her job without hesitation and began to do meditation and breathing practice. She did so out of her eagerness to solve the most basic issue of life. After several years of extreme practices she met her Original Nature and reached the level of Enlightenment in 1994. She has reached the level of the Universe and is now serving as a guide showing the road to those who wish to reach the destination.

Master Mun has written over 20 volumes regarding Seongye Practice, which has had a major influence on the world of meditation training in Korea. For the first time, she describes the entire picture of the Universe, its various realms, from the lower souls to the higher levels of divinity. All religions, all paths, all roads are included in the Universe, she says. The Universe is a different concept to what we have learned so far.

Master Mun currently resides in S. Korea.
