Each one of us is a subjective instance of observation, made out of the whole, other people, the laws of our universe.
Essentially, almost nothing is ours; everything we are made of existed before, and the ways we are molded into individuals are shaped by forces beyond our reach. The only thing that seems like truly ours is the being itself, but still this is our core ingredient that we share with everything else conscious.
We are just a viewing angle of the whole, a monad, observing a part of existence through the tools we were given by the One itself.
