S6E17 LIGHT CAVE LESSON

What were the series creators trying to tell us in their story? What were the lessons we were supposed to glean from their tale?

The light cave where Desmond pulled out the stone stopper, and where Jack replaced it was the heart of the island. This cave is the center of the LOST mythology and end game.

When the stopper was pulled out, the light source was turned off; evil was released (island began to have earthquakes); and the supernatural turned natural (Flocke into human form).

Likewise, when the stopper plugged the hole, the light source was turned back on; evil was trapped; so did the natural turn into supernatural(?)

The light was explained as being in everyone (is is "life, death, and rebirth.") The writers are referring to a universal soul concept, where everyone is connected by one giant life force.

However, we know from experience that darkness, evil is also in everyone. So why was there a need for a stone stopper on the island to keep evil at bay?

Once the evil was released, it appears to "consume" all the light (soul). It would turn everyone evil. As Flocke complained, it would take away "humanity."

So the lesson is that humanity is the balance between light and dark.
