The Sun.
Sun, settling after a journey west shares a mystery that cannot be approached-
Heat, it brings periodically.
For fear of burning others, the curious and the not.

The Moon.
Moon, moves on a path eastern by it's own whims. It moves along with a determination and speed of it's own. Cold, till understanding of warmth in the night sky is reigned in.

The path along which they run.
Heavenly bodies, mysterious in their ways and movements; cross paths,
Eventually.
When they meet, do not stare; for who is really to say who may overlap the other?
And, do not stare-  The coldness is merely the absence of heat, and the heat itself longs to be balanced at pace with it's own absence.
Do not stare, for you may notice the race for pacing of these forces on heavenly bodies,
And be blinded by their immensity.
