The word "命运" is formed by combining two distinct but complementary concepts, each represented by a single character. The first character, "命", carries the sense of a mandate, decree, or the unalterable course of one's life, it implies a fixed, inherent destiny. The second character, "运", introduces the idea of movement, fortune, and the cyclical turns of luck or circumstance, it is the variable, dynamic force of life's journey. Together, they create a unified concept where the predetermined ("命") interacts with and is carried forward by the flowing, changeable events ("运"), embodying the complete idea of fate as both an inherited path and the unfolding, often unpredictable, experiences that realize it.
