Esotericism

Esotericism, properly, is the study of transmitted and secret knowledge of any kind. While the knowledge is generally philosophical or ethical and mystic, it can, in theory, be of any kind.

Many groups or schools of thought embrace an esoteric tradition or philosophy:

• Freemasons?
• Kabbalists
• Esoteric Buddhists
• The (fictional) Rosicrucians?
