יסוד נקרא כל, כי שם נכללו כל המדות העליונות, והוא המחבר כולם ומשפיע למלכות הנ(ק)רא כלה, גם כן לטעם זה שנכללו בה כל המדות גם כן, והצדיק הוא גם כן שמחבר כל המדות, וכמו שכתבתי על פסוק אשר יוציאם ואשר יביאם בשם מורי כו': (תוי"י פ' לך די"ט ריש ע"ב).
Yesod is called “All” (kol) because all of the supernal attributes are included in it. It unites them all and shines [them] into Malchus, which is called “the Bride” (kallah) for the same reason, that all the attributes are also included in her.6The words “All” – Kol, כל, and the word “Bride” – Kallah, כלה, share the same root - kaf lamed. However, the word Kallah has an additional letter hey, which corresponds both to the Sefirah of Malchus and to the last letter hey of the Tetragrammaton. Malchus, like Yesod, is also a microcosm of the entire Sefirotic realm. However, Malchus is feminine and receptive, whereas Yesod is masculine and imbuing. Likewise, the Tzaddik unites all the attributes, as I wrote on the verse: “....who can go out before them, and come in before them,” in the name of my Master. Toldos Yaakov Yosef, Lech Lecha, p. 19b
