(I went to a charnel ground for the practice of Chod a few dozen times in India and in Nepal. Several times I went to a place near a meat slaughterhouse where thousands of water buffalo bones were piled high in macabre pyramids. One night as I was chanting, the bones began to shift, move, and rattle about. I didn't think it was a ghost or demon, but I did imagine that some kind of huge rat or snake was making its way through the immense pile. I must admit I was scared out of my wits, although I somehow managed to keep chanting, praying, and practicing the somber meditation and visualization until dawn. Was I ever happy when that night ended!)
