Hazmat yes I think you are correct regarding the existence of an unseen flaw in the stone. According to the late poet philosopher Leonard Cohen, "there is a crack in everything, that's how the light gets in". He is also the sage who saw his lovers "flag on the marble arch" revealed in a stanza of his great mythic hymn 'Hallelujah' I would be interested to hear what Athar doth believe, since the imagery here transcends particle metaphysics not to mention geology. The few I times that I encountered a flaw in a piece of stone, I had to make an adjustment in proportion and depth to minimize the flaw. Another time I drilled a hole in the fractured pieces and put a rod thru the 2 pieces. The seam was barely noticeable. Sometimes the same kind of thing happens in relationships.Damage repair and recovery become part of the finished work.
