Oscillate

Trapped in a cavern, it's pitch black and the air is getting harder and harder to breathe. Disoriented, hands follow the walls to find what could be the ceiling, fingers digging into the rock to find something- anything- loose to help point toward a direction out. Suddenly, a rock frees itself and after clearing away some dirt, a pin of blinding light shines through the enveloping darkness. Clearing away soil and rock with more and more vigor, hope and salvation is just a short way from here.
