Today is Day 19 of my meditation challenge and the centering thought is "Joy is my highest purpose." Of course today seems anything but blissful in the aftermath of the Vegas shooting. As reports came streaming in yesterday I was truly saddened. It made no sense. What makes a man of 64, with no criminal background or any warning signs, go out and kill innocent people? The account of what happened, the lives lost, the terror that ensued is heartbreaking.
