Hanol-gyo (, Hanol gyo or Hanolgyo) is a Korean traditional religion based on the philosophy of Spiritual Transcendence, re-established by Shin Jeong Yil. Hanolgyo can be considered as a religious re-establishment of the national founding philosophy of Korea which foresaw the possibility of an evolution in human consciousness 5000 years ago; it laid the spiritual foundation for the old Korean empire Gochosun (Gojoseon).
The progenitor of Hanol-gyo, Dangun (the founding father of Korea who established the old Korean empire, Gojoseon) initiated the principles of the Hanol Spirit (the teachings on Enlightenment and Awakening) introducing the possibility of spiritual transcendence to its people: the evolution of human consciousness from the ego-state to the transcendental-state.
After 5000 years, the principles of the Hanol Spirit were consolidated into a religious foundation by another awakened being, Shin Jeong Yil, the founder of the Hanol religion (Hanol-gyo). Dangun's famous dictum, well known as the founding principle of Korea is to "unite and benefit all in existence-홍익인간 Hongick Ingan”.
Hanol principle is the teachings on enlightenment and awakening; it pursues self-liberation of consciousness rather than the traditional ways of religious worship.
According to the Official Guidance to Hanol-gyo, Hanol-gyo is an unconventional religion: it allows its participants to practice other religions as well. It regards all enlightened beings ( Dangun, Buddha, Jesus, Lao-tzu, Confucius, etc.) as teachers of enlightenment and awakening, and various religions as the pursuit of Universal Truth in different ways. Its aims are to understand and practice Universal Truth, and to overcome all forms of segregation (e.g. Religion, Race, Ideology and so on).
"The founder's Doctrine "Na-Ol is Han-Ol" means “My spiritual essence is the spiritual essence of Han”" HAN is a profound word symbolizing Infinity & Totality and Universal Truth. The native name for Korea is Han Kook, meaning "the Nation of Han".
"Hanol-gyo helps to find one's true nature (Na-Ol) which is one with Han-Ol, and fulfill one's true nature by practicing love, wisdom and devotion — the will of Absolute Benevolence."
In the churches and temples of Hanol-gyo, there are no figures to worship: instead there is an "Empty Chair" that symbolizes the invisible and silent nature of one's true essence beyond one's physical form of self and mental form of ego — the Na-Ol. The invisibility and stillness also reflect the essence of Hanol, which is ultimately one with Na-Ol.
