When a person focuses on what he (or she) sees and reacts to it and especially seeks to control his environment, he lives in a dualistic (or polyistic) state wherein lives his struggle to find non-struggle and peace and fulfillment. The illusion is what is sensed through these five senses and having perceived this as something different from something else. Thus, simply, the illusion is distinguishment -- such things as evil and good, cold and hot, white and black. When these things are reacted to and conformed to by behavior in some way, it indicates a mind in a limited bubble, bound by the illusion of duality -- and in this way, not privy to ultimate truth; and in this way, not free, subconsciously lonely, and in the dark -- all, obviously, to varying degrees with each person, depending on how much, for whatever reason, he focuses on his duality and reacts to it.
In what I refer to as the 'Mindscape', where what is inherently consciousness is free of the struggles of the illusion of a distinct self and self-protection and fulfillment, there is the plane that is transcendent of perception based in the 'tangible' or more 'physical'. This place is like an infinite blue sky that is as infinitely large as it is small. In perception of this is a place where consciousness dwells, a place beyond time, beyond space; thus there is no time, and no space. All reality is held in a expanse of nothingness wherein everything within it touches everything else. Total knowledge is here -- it is the realization of one truth, it is what to more muddled perceptions might be referred to as omnipotence, enlightenment; and when perceived is perceived means to communicate telepathically, to know clairvoyantly and prophetically, and to control and manipulate the various tangible (physical) and non-tangible 'distinguishments' that are the reality on the '! lower' planes. To a perceiver focused on the distinguishments, and on the illusions of time and space, such phenomena of the mind appear miraculous; but they are only the result of some 'total spiritual', and mentally-free perception in an individual.
