Greetings from your Higher Self, the part of you that you consider to be in communication with the being that you term "God."
I would like to take the time to clue you in to the matter of this "big bang" that you compare to having the force of many types of your atomic and other physical matter.
Before this universe existed, all there was, (so far as I have been able to surmise; I'm only your Higher Self, not the Creator) was a very large void.
This void had nothing in it, save for a non-physical point of reference known as Consciousness. There wasn't any--again, only as I surmise--type of physical matter, whatsoever.
This Consciousness, so far as I am able to tell, was composed of a sub-layer of many different types of energies, all cascading within, apart, and as part, of each other. Together, they made up this one little point of reference, of that Consciousness within that void.
Getting back to the 'big bang' mentioned earlier: Your 'big bang' was an intriguing event; however, it had no noise, so to speak. How could it? How could someone hear a burst of PURE LIGHT?
Consciousness had to move, relative to itself, in the void, as a void has no dimension. Consciousness moved, relative to itself, as it had nothing else relative with which to move, in one direction (say 'up' for the sake of argument, although all direction is relative in a void, just like empty space).
It moved up. Then, it moved out, side to side. One dimensions. Two dimensions. Then it moved front to back. Three dimensions. This, my dear Human, is oversimplified to make a point, just to be honest here. The actual process is non-physical and beyond even I, your Higher Self, although I am still studying.
It then went through a division not so dissimilar to cell mitosis, then, through a complex pattern of geometrically-linked, mental-dynamics, expanded outward, sending out parts of itself to explore the void.
Some parts came back, some parts disintegrated upon sending. Keeping this journey simple, only those parts that were bound together with the mental-dynamic aspect of Pure, Unconditional Love [this being what might be termed a type of spiritual *Energetic* <used here as a noun>].
What this 'Pure, Unconditional Love' did was to show to the Consciousness that sent it what type of binding agent was needed to hold together the parts of itself that it sent out to build a particle-waveform universe in which denser matter could exist in; or, for that matter, to prove that there was even any type of existence possible in what was, before, a void.
The 'big bang' was the original Consciousness extending itself into a lightform universe, kind of like a giant, all-encompassing hologram with quantum-field sub-structure (modulated by and related to thought, but it's a bit complicated, so I only touch upon the subject here), but with denser physical properties than the original void.
What it means is that we live in a universe, wholly-encompassed of light. All you see is Light, including yourself. Even I, your Higher Self (I am an aspect of Mentation, or 'thought-at-work'), am made of Light, although considerably less dense than your physical body. The Mind, or 'that-which-you-know-to-be-you' exists outside of the physical structure that houses what you term the spirit. It's a dense construct, created for you to play around in for a while, then leave, take what you've learned with you--taken in the form of dense, compacted mental-thought-material distilled out of your life experiences and formed into usable packets of Pure, Unconditional Love (once again, an *Energetic*), that contains within itself every memory and experience of your lifetime.
This packet of distilled life-experience adds to what you were before you took on a physical body, adding to a new, 'Entire Whole', which will, one day, combine to form a new Entity or Being, which may, perhaps, desire to become a Creator, which may create yet whole new universes in which to play. I am almost positive that this is the case.
So, dear Human, let's review:
The 'big bang' was, in fact, a burst of Conscious-Thought-Mentation, which, in and of itself, was the very substance of Light.
You were born from Love. Pure, Unconditional Love. Love that binds every aspect of your existence together, so that you may exist and experience.
Your prime goal is to experience and send these experiences back to the Creator. Your physical existence accomplishes this by confining your normally-expanded consciousness to a single physical form. This may happen many times. Whenever the collective consciousness of what-you-are decides it wants to learn something new, or in a different way, it takes on one, or many other physical forms, in different places, times (temporally-speaking, this means any era that exists on Earth or that has ever existed. <we won't get into other planets here, its just too difficult to explain to you right now at your level of Awareness.>
This is what is termed, by Humans, 'reincarnation.' I set the word in quotes because it really has more elemental nuances, or parts, to it than is normally understood. It is simply that aspect of Consciousness 'making the rounds' to gain experience.
Along the way, we meet others doing the same thing we are. Because of the thought-mentation distillation process going on here, what you do to each other as Humans has a very profound effect on what you leave with when you drop your physical body, at the point of life termed death.
Sometimes these distillation patterns keep the Pure, Unconditional Love from forming properly, temporarily 'mucking up' (if you will) the works; things have to be 'cleaned out' at this point.
Sometimes a new lifetime might be lived. Sometimes outside help can purge the muck from the works, allowing that one individual facet of life-experience (that-which-you-know-as-you) to continue on, without impedance, to join its collective soul group.
This goes on until the collective group of life-experience-facets gets enough mass to move as One, heading back to the Source Creator, adding to the original Consciousness, as well as expanding on its own forays into Consciousness and Experiencing.
My dear Human. Please heed this message from your Higher Self. Above and beyond everything that is good, just, holy, and pure. WAKE UP!
Narrow viewpoints occurring within One Mere Lifetime tend to 'muck up the works' of your spiritual growth, clouding your much larger Higher Mind (of which I am a component.)
I suppose, here, you want an answer, after all that rabble. Well, I don't have the answers. I have given a painfully-brief outline of what I have as direct, personal experience (in the form of transmitted thought-mentation energetics) from our collective 'overspirit' (if you will)
What our job, together, is, is to do one thing: EXPERIENCE! I am contacting you through this other Human "GongElder" as this being seems receptive and is willing to type fairly fast ;-) (even we Higher Selves can have a sense of humor, can we not?).
I am mirrored across your Earth in the faces of other dear Humans. We are all connected. We have invented religions of our own accord. No one else created them. We did! Alone, we have have mired our True Selves in our own version of what you term 'sin.' Sin, in truth, is not realizing just who and what we are. We are Light! We are Love!
Pure, Unconditional, Love!
Dearest Human, I, your Higher Self, leave you with the most profoundest depths of Love. --YHS
