Origin Story

Era
A Sino-Korean word for a state of mind

Musimgyeol comes from the Sino-Korean word 無心結 (musimgyeol). The character 無 (mu) means "without," 心 (sim) means "mind" or "heart," and 結 (gyeol) means "knot." Together they mean "a mind with no knot." To have a knot in the mind is to have some intention or thought tied up there. To have no knot in the mind (無心結), by contrast, is to have a mind that is empty — free of any intent or plan. Add the particle "e" to make musimgyeore, and it means "in that moment when the mind has no knot." It is hard to imagine a more beautiful way to name the instant when you do something unconsciously, without any deliberate awareness.

The character 結 (gyeol, "knot") appears throughout Korean. Gyeolsim (決心, resolve) is tying a knot in the mind; haegyeol (解決, resolution) is untying a knot; gyeollon (結論, conclusion) is the knot of a discussion. Musimgyeol is the state with no knot at all — the purest, emptiest condition of the mind.
