The source is the opposite of the beginning. The beginning is eternal and always happening, and you can never see the end because you can only see the beginning. The beginning is everywhere around us and we can't look anywhere without seeing the beginning.
The source is different. The source is at the center of the core of the earth and is one small, infinitesimal point...but that point is also cut in half and then cut in half again and then again and again again again again again again...forever.
The source has become so concentrated that is not visible, it is not material, it is not logical, it simply is. You can't see it and yet the entire universe is contained within it.
That's where the Big Bang came from – look what that created.
Where is your source?
When was its Big Bang?
What will it create?
Who will help you find it?
