the universe contains everything and nothing. that's why and how all possibilities can play out, ultimately. so it's infinite in nature and in descendance. in mathematics, if you divide by 0, it's always infinity, regardless what is being divided. and well by that you get that what the universe actually is: infinity. dividing 0 by 0 is a different story, because it's infinite, but at the same time it's one. so, i guess the universe contains X/0 and at the same time not, which could be the reason for it going on and on for ever more....... or not at all ??? who knows.
obviously infinity can be broken down and be inspected and well... with limited imagination, how would you be able to imagine infinity, tell me! separation takes place in the mind, formation of bounds and boundaries are formed in the mind and with the creation of a "mind" (or many) within a brain, automatically separation itself is being created, which is of course illusion, but well... considering that everything else is basically also illusion doesn't make that look too bad i guess.
so mind is illusion and that's logical, as the 3rd eyes of most people aka thoughts are having are being dominated by dark clouds or other mysterious dark forces. that's the point when/where perception becomes infiltrated by the lies within, that try to guard themselves by fooling YOU. so you can live enslaved either by yourself or others or you can choose to be free.
