The [Dark Side] Cave is a mysterious location on Dagobah that is strong with the dark side of the Force. Those who enter the cave are not necessarily part of the dark side, but they will experience the darkness within themselves. While visiting this location may be dangerous, it is a necessary part of the hero’s journey.
Similarly, we all experience darkness on this planet. However, just as the fish in the sea do not have to be salty like the sea, we within the darkness do not have to be full of darkness. We must pass through Earth as part of our journey, but we can be a contrast to the corruption that exists.
Facing our fears is the only way to survive the cave. And, what’s in the cave?
