There is the little"I" and the big "I", when they are brought together they cancel one another out without destroying one another. Sort of like the yin, yang symbol. You seem to be an individual little being who goes about his or her individual business daily. Yet one can never be separated from the larger ocean of "I"s, of individual beings and forms which are all interconnected. It is painful to live from the limited perspective of little "I", yet it is also too heady to live from the perspective of interconnection, the oneness of all things. There is an in between place where heaven and earth unite, mind and body become one, where sitting on the meditation cushion is the same as every other moment of your life. When heaven and earth unite, the precepts become common sense and not just abstract moral rules. The precepts become perceivable truth and wisdom.
