This work presents a scientific inquiry into the physiological and psychological grounds of ‘sense’ and ‘engagement’ in three phases namely emergence, recurrence, and reformation. Based on bio-field approaches to consciousness, this work proposes that sensation is a result of state changes in an underlying bio-field of a cellular matrix, a wave complex of fundamental energy particles’ propagated energy in space–time continuum. Functioning as the mechanism for information acquisition and transmission of sensory systems and information processing of neuronal activity in brain, this field is posited as the determinant of sensory perception. Using wave theory principles, this work proposes that the waveform or oscillation patterns in this field and the super-position and resonation they undergo whenever electro-magnetic signals of similar type are generated in neuronal processing, determines the collective response of the bio-system. Using neuronal correlates of consciousness theory, this work proposes that at alpha-theta-delta electro-encephalogram (EEG) regimes, this bio-field goes through 1. non-occurrence of usual sensory related waveforms and 2. resonation with signals external to the bounded field, and thereby develops new patterns, a process termed reformation. Harmonizing biofield energy flow, is found to influence emotional regulation, stress reduction, and mood, which are key contributors to happiness. This work makes an essential theoretical contribution on understanding the mechanisms of sensory perception on the basis of bio-field electro-magnetic wave theory and the process of reformation to reach overall emotional well-being.
