This is the first principle of metaphysics. Assumptions are unproven, unproveable positions upon which thought, words and deeds are based. Every thought, word and deed are based upon, hinged upon metaphysical assumptions. Creation emerges from the All. The All is the primordial unconditioned space of original innoscence.
Duality is born.
Father and Mother , Positive and Negative become the first distinctions. Paradox is born. The interaction between the All and the Nothing became the first paradox - Alpha and Omega, the beginning and the end. All exists concurrently in No Time. What Is, simultaneously, Is not.
