This picture depicts a Chasidic Kallah doing a Mitzvah Tanz. She stands there - face fully covered (including her eyes), standing straight, not moving a muscle while holding on to a very long rope or belt while Chasidim are asked one at a time to come up and 'dance' with her while holding the other end of the rope. What in heaven's name are they doing? Why is this done? What kind of holiness does this represent? ... at the wee hours of the morning?!
