Candle lit. The room quiet enough that you can hear the wax settle. Nothing left on your list except this.
The stone on the nightstand
Clear quartz, catching the candlelight, set down next to the water glass and whatever book didn't get finished tonight.
Amplifying, not doing
An emitter, associated with clarity — not adding anything new, just making a little more room for the one clear thought that's been waiting all day to surface.
Lights out
Just the stone, catching the last bit of light before the candle goes out too.
Let clear quartz be the last clear thing you notice before sleep.
