In a famous chapter of his Principles of Psychology, William James analyzes our perception of reality. He pointed out that we lived in different mental words, like parallel universe . According to him, there are several, probably an infinite number of orders of realities, each with its own special and separate existence. James called these "sub-universes". The human mind conceives all these sub-worlds more or less disconnectedly, and when dealing with one of them, forgets for the time being its relations to the rest. These realities are experienced as mental sub-universe, and can be shared by more than one person. John Whiteside Parsons (birth name Marvel Whiteside Parsons), October 2,1914 to June 7,1952, was an American rocket engineer, rocket propulsion researcher, chemist, and Thelemite occultist. Associated with the California Institute of Technology (Caltech), Parsons was one of the principal founders of both the Jet Propulsion Laboratory (JPL) and the Aerojet Engineering Corporation, helping to develop the solid-fuel rocket and being one of the participants in the beginning of the space age. Over his short but incredible life, Parsons was a bit of a creative genius in two key areas - the occult and rocket science. Living in multiple realities, the physical world, and the paranormal one.

It is possible that while performing this ritual, Parsons opened a door or a gate, and something flew in this world. The assumption behind is that Crowley first made contact back in 1917 through the Amalantrah ritual with Roddie's entity. Later, Jack Parsons practiced a similar ritual (the Babalon ritual) with Elizabeth Cameron, and with the assistance of L. Ron Hubbard, as a mystical medium. These rituals reopened the portal Crowley sealed years before, but this time Parsons created a bigger fracture in the space-time continuum. The Babalon ritual is patterned after the Amalantrah ritual. However, this latter portal or gate could not be seal due to Parsons' inexperience, la
