The fundamental function of human brain and sensory organs, based on empirical experience, is to communicate what we visually perceive and what is significantly linked to memory. The Absolute nature of the physical world can be understood, by an epistemological study and retrospection of sense perception and memory. This analysis can be done by a few simple tests from day to day experiences. It is also done to identify the well-known EEG signal data of individual's waking, dream and deep sleep states. My study substantiates the fact, that in an absolute sense, the human brain receives the external reality of the physical world through sensory information. When a sensory neuron is excited by electromagnetic light waves or sound waves, or other external stimuli, the brain registers it. Except for routine matters, the knowledge [of physical world] received by the brain is relatively conflicting, unnecessary and non-scientific. This phenomenon could be attributed towards the making of a “Conflict free” personality though with a caution. “Knowledge must be practiced with wisdom”.
