There’s two dimensions to life, one mental, one physical.
In the physical dimension all things are so interconnected as to be one whole thing. In the mental dimension the same thing applies. The observable universe is God, the mind that looks out from you onto the material world which is the body of God is also God.
In the beginning there was nothing, so God created the universe out of himself. Likewise there was no one else so God peopled the universe out of himself.
All is God.
