 The ONA utilises two methods in its performance of aeonic magick . The first entails rites and chants with the intent of opening a gateway – known as a " nexion " – to the " acausal realm " in order to manifest energies in the " causal realm " that will influence the existing aeon in the practitioner 's desired direction . The second method involves playing an advanced form of a board game known as the Star Game ; the game was devised by the group , with the game pieces representing different aeons . The group believes that when an initiate plays the game they can become a " living nexion " and thus a channel for acausal energies to enter the causal realm and effect aeonic change . An advanced form of the game is used as part of the training for the grade of Internal Adept . According to Myatt , he invented the game in 1975 .
