Acharya Prashant addresses the classical Upanishadic description of the universe as a human being, clarifying that this concept is symbolic rather than literal. He explains that in spirituality, such descriptions must not be taken at face value. The core idea is that the universe and the human being co-exist and are essentially one because the universe appears as it does only because of the human observer's specific physical and mental configuration. If the human brain or senses were different, the universe would appear entirely different, as the brain acts as the processor or compiler of reality. He illustrates this by noting that the appearance of objects depends on the brain's processes, citing examples like how drugs or physical trauma can alter perception. He points out that humans are limited to specific visual and aural wavelengths and a three-dimensional perspective. If these fundamental configurations changed, the entire universe would transform into something unimaginable. He concludes that because the universe is coexistent with the mind, different beings, such as insects, experience entirely different universes and time scales. Therefore, the statement that the universe is human is a subtle spiritual truth about the interdependence of the observer and the observed.
