Every ancient culture has had a God to represent some form of human existence. We see this in ancient Egypt and all over especially in the Hellenist civilizations. The Egyptians had hundreds of Gods to represent every calamity, desire, emotion, lifestyle, food, feeling, animal, everything.
Humans are prone to repeat history because most of us are not historians nor can we evolve past our basic human instincts. The only way past this is knowledge. When you can recognize a manifestation in yourself or out in the world you can technically track it and watch it wax and wane, take root, or wither away. Even find its source.
The study of history is the study of human action and reaction and the reasoning behind it. You almost not need to know why but just that it occurred, as humans are predictable and will fall for the same old trick again and again. This is were knowledge of the past comes in handy when you have a world to govern. One variable of occult study is of human behavior, once understood people are able to level the playing field for themselves and even ascend it completely.
The occult just means obscure or hard to understand. Many philosophies are; “The lips of wisdom are closed, except to the ears of Understanding"—The Kybalion.”
