6. Rabbi Elazar said: There are three supernal holy lights, NAMELY THREE LINES connected together, in which the whole Torah is comprised. They open the gates to everyone AND HAVE INFLUENCE on Faith, WHICH IS MALCHUT, and they are like a house to everyone. Therefore, they are called 'a house,' for THE THREE LINES OF THE BET ALLUDING TO THE THREE COLUMNS OF ZEIR ANPIN are a house (Heb. bayit). The Torah commences, therefore, with that letter, for it is a house and a remedy for the whole world.
