During a lunar eclipse, the red on the moon is every sunrise and sunset on Earth at once. Even shadows can carry light.

Shadow and light are not exclusive. The colour exists because light bent around the edge of the planet instead of being blocked, so the dark part of the event is the part doing the work. Hard stretches sometimes behave the same way. Something gets through that could not have arrived under ordinary conditions.

You do not need to look for a bright side in whatever is difficult right now. It is worth staying open to the possibility that something useful comes through the edges, often a person, often later. Noticing it is enough.
