Esoteric refers to knowledge or practices that are intended for a small, specialized group rather than the general public. This term often relates to spiritual, philosophical, or mystical traditions that require specific insight or initiation to understand fully. Examples include certain teachings within Gnosticism or Kabbalah, which are not easily accessible to everyone. The concept of esotericism can also apply to various fields, such as alchemy or occultism, where information is often hidden or coded. This exclusivity can create a sense of mystery and allure, attracting those who seek deeper understanding or enlightenment beyond mainstream beliefs.
