Existence is its own ‘origin’, as awareness is aware of itself, (though not in a self-reflective subject-object relationship) as well as of everything else; or as the first cause is the uncaused cause, the unmoved mover of Aristotle, Plato, etc. Existence IS. It is the super ‘Big Bang’ or prior to ever being a Big Bang, for it is a metaphysical principle, indescribable, unexplainable, and having no parts – the ’given’ and originator of all things, without which nothing is. It is, in fact, the arché, first or highest principle or noumenon – consciousness or reality itself. Before anything existed, existence was/is – that is its mystery.
