ViHiskadishtem ViHiyisem K’doshim 5745.

This Maamar discusses holiness. not in the shul or Yeshiva but at the table. The holiness of the table (connected to washing, Brachos, Tzedaka and Torah) holifies the meal and contributes to the purpose of Avodas HaBirurim most substantially. It also mentions the idea that our holiness ‘holifies’ Hashem Himself (also).
