Esoteric teachings or knowledge; the system or practice of esotericism; secret doctrines.
From 'esoteric' + '-ery' (suffix indicating a place, practice, or collection). The '-ery' suffix (as in 'bakery,' 'sorcery') suggests both a location and a domain of activity.
Esotery sounds like an archaic term from fantasy novels, but scholars still use it when discussing historical traditions like Gnosticism or Hermeticism—it's one of those older English words that perfectly captures the idea of a hidden realm of learning.
