The beauty and delight of Malchut are only in her when Yesod is with her, for through Yesod she becomes complete, whereas when Malchut is without Yesod, she is the source of all deficiency and sadness. But when Malchut is with Yesod, she is the source of all joy for the male himself. Accordingly, at first everything was in the mystery of BaN, which is Nukva (the female) without the male, which is the source of all sadness. And the Six Directions (Zeir Anpin) did not turn to Malchut, because they did not receive delight. But when Yesod came in the mystery of MaH, she was then completed and she herself arouses delight in the male himself, and this is the repair.
