as a compliment of concentration. in eccentration, one uses the peripheral vision as a "
focal field ". the eccentrationist or eccentrator gazes into the distance with no fixed-point on which to focus. as such, he / she becomes aware of everything happening in the
periphery and can use
infinitum as the distraction...as a compliment to contraction.
many people choose to exercise / stretch in front of a mirror. this allows the practitioner to " focus " on their reflection and make
judgements and corrections based on their evaluation. if we choose to gaze into the distance ( eccentration, be it 10 feet or 10 miles ) and NOT focus, we have only our
periphery to shape our field of vision. and we have only our proprioception to gauge our alignment / progress. some
yogic traditions hold that attachment to forms / things is the source of suffering. forms and things become indescernable when we " eccentrate ".
