The following is my attempt to formulate a "theory of everything" that is as short and concise as possible and doesn't contain any kind of unnecessary fluff. I hope you have fun with it... and please keep in mind that this is only a conceptual model which, just like any model, is nothing but a necessarily incomplete and ultimately inadequate abstraction. Enjoy. --- The Absolute is the totality of Being. It has no specific quality, as it is the origin, the sum, and the essence - or field - of all possible qualities. Therefore, the Absolute cannot be directly experienced; an experience is always the experience of something definable, i.e. of something that possesses a concrete quality. In other words: Reality is only ever partially perceivable, experienceable and cognizable, but never as a complete whole. Consciousness or experience of reality is therefore only possible where the Absolute seemingly splits up into several parts and establishes contrasting relations between them; it is the contrast between these different parts (or states) that gives them their specific qualities and thus makes them experienceable. Relativity is thus a necessary condition of existence: No relations -> no contrast -> no qualities -> no experience / cognition of reality. In order to perceive itself, the consciousness of the whole, which can only ever be experientially aware of specific parts or aspects of itself, must constantly alternate between contrasting qualitative states; therefore, no state can ever be permanent. However, a state can appear more or less permanent if the speed or vibrational frequency with which consciousness shifts between contrasting states is accordingly low (-> one-sided fixation, relative stagnation, seeming incompleteness / fragmentation, suffering). But the higher the frequency, the more consciousness approaches a holistic experience of total reality where contrasting qualitative states seem to be experienced simultaneously (-> unification and integration of all opposites, 'spiritual awakening", "enlightenment"). This is the essence of all spirituality. ---     Due to popular request, here is a more easy-to-understand analogy (which I originally posted below) that illustrates what I am talking about in the text above: This is the famous Yin Yang symbol, which I am sure you are familiar with.

Now, here's a question for you: Is this symbol white, or is it black?

It's obviously both, right?

So the symbol possesses / represents not only one specific quality, but two: Whiteness and blackness.

Now imagine a thing which has not only two qualities but literally every single quality that there could possibly be, including the quality of not having any quality whatsoever. This "thing" - which is no-thing as well as everything - is the Absolute aka. All of Reality.

This no-thing / everything cannot be experienced directly, since it is impossible to experience every possible quality that there is all at once. So what does it do in order to be able to experience itself? It splits itself up into infinite parts, each of which represents and embodies a specific quality (just as Yin represents blackness and Yang represents whiteness), and then it lines them all up in space and time so that it can experience them one by one. Now, when it moves its awareness very slowly from part to part (so to speak), then each quality that is being experienced in the moment is being experienced for a pretty long time; and the longer it takes for a certain quality (or part of reality) to be experienced, the more dense, solid, sticky and permanent it seems... even though no experience can ever be permanent (since an experience can only exist in contrast to another experience, just as Yin can only exist in contrast to Yang.)

Now, go back and take another look at the Yin Yang symbol. Imagine that you could never see (experience) the whole symbol all at once, but only one part at a time. Imagine that there is a switch in front of you that you can flip either to the left or to the right; and depending on which side you flip the switch, you see either the Yin part (black) or the Yang part (white) appearing on the screen. (Remember: You can never see them both at the same time.) - So, the only way for you to get an idea of what it would be like to see the full symbol all at once is to flip the switch back and forth as fast as possible; and the faster you flip it back and forth, the more it will seem like you are looking at the whole symbol (while at the same time the two contrasting parts will seem less and less dense and solid.)

This is basically what spirituality is about. It's about learning to flip the switch as fast as possible (by whatever means necessary) in order to "perceive the Absolute" - which you never fully do, but you can get closer and closer and closer and closer to it... unto infinity. Because that's literally what the Absolute is: Infinity aka. All there is. Hope that helps.
