 The ONA believe that humans live within the causal realm , which obeys the laws of cause and effect . However , they also believe in an acausal realm , in which the laws of physics do not apply , further promoting the idea that numinous energies from the acausal realm can be drawn into the causal , allowing for the performance of magic . Believing in the existence of magic – which the group spell " magick " following the example of Elias Ashmole 's 1652 work Theatrum Chemicum Britannicum – the ONA distinguish between external , internal , and aeonic magick . External magic itself is divided into two categories : ceremonial magick , which is performed by more than two people to achieve a specific goal , and hermetic magick , which is performed either solitarily or in a pair and which is often sexual in nature . Internal magick is designed to produce an altered state of consciousness in the participant , in order to result in a process of " individuation " which bestows adepthood . The most advanced form of magick in the ONA system is aeonic magick , the practice of which is restricted to those who are already perceived to have mastered external and internal magick and attained the grade of master . The purpose of aeonic magick is to influence large numbers of people over a lengthy period of time , thus affecting the development of future aeons . In particular it is employed with the intent of disrupting the current socio @-@ political system of the Western world , which the ONA believe has been corrupted by Judeo @-@ Christian religion .
