Logic... Amusing! Logic discusses causes and effects, and fails in every attempt to find a cause without cause.
Things follow things, (logic) so things ultimately cannot have ORIGINATED - if anything is to be, it must be some effect of some cause, no? No.
Logic fails when it comes to co-creation. Things are defined by what they are not - things have properties distinct from other properties they do not have. Ultimately, Existence is such in contrast to Nonexistence - and Nonexistence is only such in contrast to Existence = Creation.
This is all as real as anything else... The fact that none of it - that which is and that which is not - is REAL (talking more of objective, subject-independent existence) is what allows for a subject of experience in the first place. Or thereabouts...
Closing the door on questioning reality never came out of understanding - it's laziness in pursuing a satisfactory answer. Those who attain to understanding are those for whom the door remains open.
