So it is said that a Sheikh chanting "There is no [Reality] . . ." disappeared and became visible again as his chant finished, "but God," and so he winked on and off like some cosmic blinker as the song went on.
This time of singing is called "The sword of Light," and it is said that a sword is whirling in the air which will cut off the head of anyone who stands before the chant ends. . . .
