What is Esoteric Masonry?
Esoteric Masonry is the personal exploration to some of the less mainstream areas of the fraternal society. Some of these aspects include personal development, spiritualism, mysticism, and so on. It can include aspects of its history not commonly looked at by mainstream historians or participants. Also, it investigates lines of religious thought that exists on the fringes of mainstream doctrine. Investigation does not mean they work to prove (or disprove) one aspect or another, to the contrary, the esoteric side of masonry seeks find additional sources of wisdom and understanding.
Interest in Esoteric masonry is starting to make a comeback. Not that its pursuits ever disappeared, certainly aspects have shifted in focus. It looks at aspects of personal resonance with the symbols of Freemasonry and helps develop our own faith. It can be very rewarding and fulfilling.
But this is not strictly what masonry is, but one aspect of it.
