What is Great Radiance in Taoism什么是大光明
"Da Guang Ming" (大光明, "Great Radiance") is a term used by the Longmen (Dragon Gate) lineage of Taoism to define the content of True Nature (zhen xing) from the perspective of luminous states. It holds that when a person receives True Nature from the body of the Dao, they receive within them a single point of radiance. Cultivating one's nature through the Dao means expanding this radiance so that it grows ever greater, until it "accumulates into Great Radiance" — a state of total luminosity, pure and brilliantly clear, in which the nature merges and becomes one with the Dao.
The Beiyou Lu states: "The radiance within a person must not be allowed to dissipate. When the radiance is great, the nature is great; when the radiance is small, the nature is small. Using this radiance to illuminate other things, nothing true or false escapes detection. To turn the radiance inward in self-illumination is to keep the radiance entirely within oneself — only those with genuine aspiration can hold it and prevent it from scattering." It also states: "If a person uses will to command Qi and does not allow it to dissipate, it transforms into radiance and accumulates into Great Radiance." This links the nourishment of nature with the refinement of Qi: on one hand, one expands and accumulates radiance and uses it to illuminate the self and all things; on the other, one employs will to command Qi, preventing its dissipation so that it may transform into radiance. Thus refining Qi also nourishes the nature, and the two are naturally united through this luminous state of the nature-body.
