Ray

ray, light

Mnemonic

Place a burning candle on a tiny stool in a pitch-black cave. Instantly a brilliant ray of light shoots outward, illuminating the jagged walls. The stool raises the burning candle just high enough so its ray pierces every shadow, filling the cavern with warm glow.
Additional thoughts
Picture the candle flame on top and the two legs of the stool beneath it—mirroring the actual shape of 光. The stool elevates the flame, letting light radiate in all directions.
Quick recall
A burning candle on a stool sends a brilliant ray through the darkness.
