The mystical formula of IAO, known by certain western esoteric traditions, is the symbolic flow that every initiate has experienced first hand (especially during an initiation rite) and during the progress of progress through grades and levels of knowledge and practical ability.
The process can be compared to the alchemical process of the refinement of the initial state of black chaos or prima materia, into the the color of white which contains all colors. This is the silver or moon state considered final by some, but the real goal is the albedo or daybreak into the solar state.
Generally this process is characterised by a spiral of going up (everything is SO good!) and then disaster happens (crap!) and then everything is good again but transformed to a higher state. You will be happy in the moment before you realise that the output of one cycle is the input for the next IAO phase.
