The kanji 精 is a phono-semantic compound. It combines the elements 米(rice) and 青(blue/green, suggesting purity or youth). The original meaning related to the purity of rice, its essence. Over time, it broadened to include the "essence" of other things, like spirit or refined qualities. The "青" component provides the sound and also the semantic indication of something pure. The rice component strengthens the essence and refinement elements.
