The mind is the agency for all cognition. When the mind is firmly embedded in the body, one can perceive the external world only through inputs from our physical organs for sight, hearing, smell, taste, and touch. When the mind is partially embedded in the body, it will be able to perceive the external world without the help of the sensory organs. Extrasensory perception occurs only when the mind is partially embedded in the body. This in/out shift of the mind induces fluctuations in certain physiological indicators. It is therefore possible to identify the occurrence of extrasensory perception through the fluctuations of these indicators.
