When R. Baruch of Medzhybizh [d.1811] was still a child he once visited R. Pinchas of Koretz. When he went to sleep R. Pinchas called his family together and said: “Do you wish to see a true Jew who is bound [davuk] with all his limbs to the Master of the World? Have a look!” R. Pinchas placed his hand over the mezuzah of the house and covered it over. As soon as he placed his hand on it, they saw R. Baruch begin to thrash in his sleep – he was restless. This R. Pinchas repeated several times and each time R. Baruch thrashed.
