Esotericism
From Wikipedia, a free encyclopedia written in simple English for easy reading.
Esotericism is about secret knowledge for a small group of people. Esotericism also describes mystical, spiritual or occult viewpoints.
In history, "esoteric knowledge" generally described knowledge kept secret from outsiders by certain groups, such as Freemasons, either to leave others out or to protect themselves against prejudice.
The opposite of esoteric knowledge is exoteric knowledge (well-known or public knowledge).
