Thus, the top point of the י', how Chochma receives from Kesser and Atik, is directly expressed in the bottom right point in how it extends and expands into the ה' of Bina. Thus, this descent of the Lofty Wisdom into Malchus is actually a very great elevation even for the Wisdom itself, for it draws down the light of Kesser, Atik, into itself, the Wisdom of Chochma, enabling it to come into Bina, and from there into Malchus.
Therefore, “And he went to his travels from the south,” referring to the level of Chesed-Kindness, “and until Beis E-l,” referring to the level of Malchus, an illumination from Above-to-below.
As illustrated, if a person is facing east, then north-צפון is on his left, and south-דרום is on his right. Since the right side corresponds to Chesed-Kindness, so south also corresponds to Kindness. The name “Beis E-l” means House of Hashem. This is referring to Malchus, which called a “house.”
The level of Malchus is referred to as “house” or container to receive this flow of Kindness and Light of Lofty Wisdom from Hashem. The name “E-l” refers to Hashem’s attribute of Kindness, thus “Beis E-l,” House for E-l, refers to how Malchus receives this deeper level of Kindness from Hashem.
Avraham’s served Hashem through the aspect of Kindness, which is how Hashem’s Light flows down to the lower levels. This is how he was able to bring down his Lofty Wisdom to Malchus, Thus, “travelling from the south” means “serving Hashem in a way of Kindness. “Until Beis E-l” means that this flow of Light in a manner of Kindness reaches all the way to Malchus, to how Hashem is manifest in the actual world.
