"...I printed, in ink, each of my separate defects on a poker chip."  "All chips went into a small pitcher.  Every morning upon awaking, I plunged my hand into it (like picking a number from a goldfish bowl) and came up with the "chip for today."  The defect might be anger, fear, pride, resentment, intolerance, and so on, but whichever one it was had to be concentrated on for the next twenty-four hours and either reduced to a minimum or cast away."
