Your fellow man is your mirror. If your own face is clean, the image you perceive will also be flawless. But should you look upon your fellow man and see a blemish, it is your own imperfection that you are encountering - you are being shown what it is that you must correct within yourself.
Baal Shem TovA broom sweeps clean, and itself becomes soiled; cleanse yourself of those offenses of which you may feel guilty.
Baal Shem TovWe should not laugh at the person who becoming caught up in his prayer bends his body or moves about in strange ways. Perhaps he moves in this manner to wave off unwelcome thoughts that would interrupt the prayer. Would we find it funny if we saw a person drowning going through strange motions doing whatever was necessary to save his life?
