For many of us, the existence of the universe itself, is more than enough proof. Logically speaking, nothing so magnificent as life could feasibly be the product of some mysteriously created random chaos. Created from what? By whom was it willfully initiated? I propose that the concept of creation itself, may have some inherently tragic flaws. It's just such so linear and relative to human thought, as a hypothesis. Existence has likely always been, an eternity in the making. :idea:
I do agree that the old "God" of anthropomorphic deification, is a product of our human need for fabricating the self-projected concept of a Supreme Being, to mirror and reflect as a polarity to the individuated mind and self (doing the analysis). Paradoxically, God/Spirit/Tao is what everything manifest or unmanifest, is quintessentially composed of, an unbroken field of being. IMO, God is what we all are in essence, interconnected by the power which holds within it's Omniscience, all the interwoven layers of mind and thought.
Adding to that, heightened states of awareness facilitate the enhanced capacity to perceive the force of this Sacred presence, despite it's innate immateriality. It is a purely subjective region of perception, however, so the whole proof issue is inapplicable. Suffice it to say, that regardless of this fact, our species has touched the Divine within themselves, lo these many millenniums passing by. History is resplendent with affirmations of this nature.
Spirit is something quite immanent, if one attunes to it's presence. For those who have exercised their receptivity and trained their intent to pierce through the membrane of this material illusion, this dream within a dream, it is most "obvious" to see. It has to do with a profound shift in consciousness. :shock:
That's just my opinion and I respect yours. Arguably, when each of us passes into our final mortal demise, we shall each see for ourselves, eh? Then, the ego-death we face under the force of psychedelics, will pale in comparison. I un-waveringly believe that I will merge within the Light of the Divine, my source and core of being.
