We 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?
Baal Shem TovIf a man has beheld evil, he may know that it was shown to him in order that he learn his own guilt and repent; for what is shown to him is also within him.
Baal Shem TovThe world is new to us every morning - and every man should believe he is reborn each day
