Research is proving that the heart and brain interact with each other which impacts consciousness, perceptions, and performance. Heart-brain synchronization can occur between two people in interaction (McCraty, Tiller, & Atkinson, 1996) when they are responding to each other with sincerity, appreciation, and love, in other words efficient communication (McCraty & Atkinson, 1999). Theories do exist that the heart contains a system of neurons-like cells that have short- and long-term memory and that their signals affect our emotional experiences when they are sent to the brain. Hypnosis experience teaches us that when people are in rapport several unconscious activities synchronize among which respiration, pupil dilatation, skin conductance AND cardiac rate.
Therefore, the Okan can align with the brain as a gate of symbolic FREEDOM, that brings the information about DREAM coming from intestine to the brain CONSCIOUSNESS. It is from this triadic relation that comes akunlegba, the free will to exercise one own FREEDOM. It is driven by Esu against the logic criticism. The right alignment between heart (emotions and analogy) allows people to effectively realize their dreams. The mal alignment between heart and brain may be expressed like an angle: the wider the angle is, the more is the freedom limitation and dream entrapment. Esu cannot exert His dynamic activity but His energetic force gradient must be directed to something. That something may be the overt expression of diseases. One could say that diseases come from the cos function of the force of the heart over the brain: D = FcosC.
