natural light, n.All

The Natural light (n.) cannot ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠speak, so it builds shapes in sleep — a fire that longs to burn, and burns the brighter the longer it is lit.

The Natural light (n.) or ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠lumen naturae was the medieval physician's second source of illumination beside revelation, to be turned to when the Church's truth failed doctor or patient.
