There are a few smaller societies or groups of higher initiates and ECK Masters, called Brotherhoods. They are formed of women and me, regardless of their current plane.

List of Brotherhoods

In alphabetical order:

Brothers of the Leaf: Contains all high-initiates (5th and more). These are souls that help Mahanta to fulfill his mission. Coworkers of The Living Eck Master.
Council of The Nine: These nine unknown ECK Masters are the guardians of ECK and Its distribution in the lower worlds.
Nine Silent Ones: These are agents of the Sugmad with a mission to gather up and sort out the unchanging laws that enfold every ripple in life.
Nine Unknown Gods of Eternity: These are the keepers of the divine flame of Wisdom. They watch over and guard the golden scripts of the Sugmad. They transform the living truth of Sugmad into Knowledge.
Order of the Mahantas: A loosely knit brotherhood of all who once served as the Mahanta, the Living ECK Master.
Vairagis: Also called the Ancient Order of the Vairagis. This is the brotherhood containing all ECK Masters. Nothing other than the spiritual upliftment of the human race have been their goals.
