Whatever problems come to us from beings or inanimate objects, if our mind gets used to perceiving only the suffering or negative aspects of them, then even from a small negative incident great mental pain will ensue. For it is the nature of indulgence in any concept, whether suffering or happiness that the experience (will be intensified by that indulgence. As) negative experience gradually becomes stronger, a time will come when most of what appears before us will become the cause of bringing us unhappiness, and happiness will never have the chance to arise. If we do not realise that the fault lies with our own mind's way of gaining experience, and if we blame all our problems on the external conditions alone, then the ceaseless flame of habitual negative deeds such as hatred and suffering will increase in us. That is called: "All appearances arising in the form of enemies". --Dodrupchen
