Some light

It's a bright sunday morning. Some light (sunlight) is filling my window. It does not feel invasive when the light comes into the room, and presses itself cleanly, like a screenprint, trapezoidally across desk and woodfloor. Sunlight (some light) is the beauty of the sun's day.

I wonder about the metaphor of light: 'spiritual illumination'. Does this entail a spirirual heat as well? Spiritual radiation? A spiritual spectrum tucked into the plain white light? Spiritual sunburn?
