If We Could See, "We" Don't Really Exist

Sorry for all the Tanya here. I'm reading through Shaar HaYichudEmunah and it's really blowing my mind. It's the foundation for a lot of Chassidus and far better reading than the earlier parts of the Tanya when it discusses all manner of souls in frequently xenophobic or misogynistic terms. So, for the good stuff:

"Every discerning person will understand clearly that every creature and being, though it appears to have an existence of its own, is in reality considered to be absolute naught and nothingness...The reason that all things created and activated appear to us as existing and tangible is that we do not comprehend nor see with our physical eyes the power of God and the 'breath of His mouth' which IS the created thing...Hence, there is truly nothing beside Him."

Chapter 3

I'm just amazed how much of this mirrors our modern understanding of physics and the manner of the creation of the Universe through the Big Bang. Obviously, the language here, like the 'breath of His mouth' is poetic; but it functions in the same way as the word matter, or primal energy, or superstrings could.
