What is existence? Where does form come from?
Imagine everything, all possible things, all possible scenarios, world's that we can't even comprehend, world's that we can comprehend all at the same time..... pure infinity. Within that frame, every single person exists and has always existed.
Imagine a large infinite pie, and someone came along one day and cut a piece of the pie. You'd have a piece of pie and then you'd have the rest of the transfinite pie that's left. Because the pie is distinct and separate from the rest of the pie there is void around the piece of pie that gives it its apparent distinctness, it's separateness. Yet the piece of pie originated from whole pie so it will always be connected to the everything else(the way it's cut will always mirror the whole pie that it was cut from).
This is where duality is sort of created from. The everything v.s. nothing, white v.s. black. To exist, one has to be both alone and together. One has to feel separate, yet one has to have something to separate from.
Some people are larger pieces of pie, others are smaller pieces of pie. The smaller pieces of pie are less distinct, have less awareness. The world around them(the transfinite remaining pie), is larger and more vast. They have no identity and are trying to find a place to to settle and grow. The larger piece of pie feels too real(the remaining pie is smaller), there is a been there done that feeling. This doesn't actually reflect what really happens though, there are different shapes of the pie, all kinds of different shapes, sizes(and reality is always changing with how you look at it).
