You can’t eat it; you can’t wear it ; it’s not pretty and it’s quite rough to the touch.but if you really want to clear up a worn or deeply soiled object ,there’s nothing to match it- all it takes is your willingness to do the job,apply the necessary effort and Voila what was once rusted and useless becomes shining and something we can use even with pride knowing what we have done.We are like this.We are like the object- resplendent with many virtues and potential but they remains dormant.The sand paper comes in the form of difficulties and our responses to what confronts us in our lives: an angry neighbor,a dishonest merchant, sloppy service, the ignorance of a friend or family member, the cruelty seen in the treatment of someone we love, injustice in its many forms. When we react to all these with wisdom and compassion and understanding- we polish our inner soul and the full beauty and potential  shines  forth and we understand and accept and are grateful for what has happened.
