So, here's a good summary of the main idea that spurred me into writing this new book. It's from the Alternative Hawaii site (click here).
There is an ancient Hawaiian myth about a place called Kaena Point (on Oahu), which was known as the Leaping Place of Souls. The souls of the dead wandered this place until they leapt into the night, thus departing from the earth. Spooky, eh? Evidently, good souls moved to the right when they leapt and those who moved to the left when they leapt fell into the pit of endless night.
