This is very similar to what the ancient Hindus believed. Advaita (non-dual) vedanta is a philosophy grounded in the non-dual nature of this Universe, and everything else including you. It takes things a step further and says “Tat tvam asi” which means “That thou art” in Sanskrit. “that” here referring to God which is not a physical god in Vedanta but a formless God, called Brahman, which is supposed to be the ultimate reality of this Universe – simply pure consciousness.
