Everything.
Everything is defined as every thing or as all. So what is everything? Everything is all that you know, all that your consciousness touches, and everything beyond ones reach or perception. Everything is the perception of all and beyond all's perception. From the sense of touch, to the glimpse of thought, to the space beyond consciousness, everything is. The expanse of everything is beyond the grasp of human imagination, though that very imagination would seek to define it as all that is within the space of perception.
Commonality.
Commonality is defined as a sharing of features or characteristics and the possession or manifestation of common attributes. Commonality is simply what two or more objects or things have in common or can agree upon. Two individuals may share a sense of commonality from a similar interest or trait; similarly a blade of grass and an oak leaf share a commonality in color, design and function. Commonality exists within every thing, or everything, as everything shares something in common with every other thing. Commonality is not limited by perception or intuition but rather is recognized by both perception and intuition.
Ultimately what I am after is that everything shares commonality. Every being, every body, every object, every cell, every atom and every gene has commonality with every other being, body, object, cell, atom, and gene. There is something beyond perception, behind the veils, concealed within the obvious that is common amongst everything. What is that thing? There are many answers, because there are many commonalities, but there are a few things that stand out such as light and vibration. Perhaps everything has a central processing station, and everything has methods of communication. Perhaps everything shares a commonality with how the observer perceives it. Perhaps one's perception is simply the interpretation of the reflection of the commonality of their perception of everything. Perhaps your world is what you make of it and your life is what you believe of it.
