It was a time period in the 1960, when a generation of souls looked at the established society, looked at the pettiness, the greed, the hate, and rejected it and tried to create something new. Their creation neither succeeded nor failed. It was another experience.
Atlantis was destroyed by the greed of its inhabitants.
As we grow up, we are exposed to hate and greed and anger and jealousy and peanut brittle and all kinds of things, our subtly body erodes.
