CONTROL SYSTEMS NEED MIND STABILITY WHICH IS VERY IMPORTANT IN SOCIETY(HONOUR AND TASTE). IGNORANCE (WHICH IS SELF or SENSIBLE-MINDFUL-VOICE) AND DECEPTION(PURE IMAGINATION WITHOUT REALITY) CAUSE "INFIDELITY(AMBIGUITY)(DEMON/DEVIL MINDSET)" AMONG PUBLIC WHICH MUST BE OVERCOME BY MIND DISCIPLINE AND MIND DISCRETION. SOCIETY IS PLURAL WHICH ONE TO TEN. BUT KNOWLEDGE(LITIGANCY)(SUBJECTIVITY) IS FOUR(ONE OF TWO BY THREE FOR FOUR). DIVERSITY IS TWO(TRUTH AND AMBIGUITY). TRUTH IS ONE WHICH APPEARS AS TWO. AMBIGUITY(INFIDELITY) BELIEVES IN DIVISIVE-BEING WHICH SAYS "YOU ARE GOOD TO YOURSELF AND I AM GOOD TO MYSELF while TRUTH IS ONE)". PL.NOTE WORLD(SOCIETY)(LAW) IS UNITY. Control systems use both negativity(zero) and positivity(one) for itself and other/s consumption. So control systems work for 'the edge to its edge". That means control systems engineer need be "neutrality while being the edge" to both use and work so that 'USE AND WORK" WILL PREVAIL AS STABILITY. POWER(TRUTH) STABILITY PREVAILS BY MAKING AMBIGUITY(INFIDELITY) SELF-ELIMINATE BY ITS OWN AMBIGUITY(INFIDELITY)(RAVANA BRAHMA). THEN RAMA(SENSIBILITY ABOUT SELF) STAYS AMONG ALL ABOUT BOTH SELF AND OTHER/S. FEAR IS RESPECTED BY SELF AT FIRST AND TO BE OVERCOME BY SELF TOWARDS HUMAN BECOMING AS HUMAN BEING AGAIN. HUMAN BECOMING MEANS INCULCATING WORK-MINDEDNESS THROUGH MIND-DISCIPLINE ABOUT "SUBJECT OF INTEREST" TO KNOW AND REALISE SELF "IN CLASSROOM OR AMONG FOUR". VERY IMPORTANT ! ANY ACADEMIC SYSTEM THAT BELIEVES IN "ACHIEVEMENT OF MORE THAN 66% MARKS" WILL BE USELESS TO SELF-REALISATION AND SOCIAL-USAGE.
