As for this Ima, the wish of both Aba and Ima never stops; they emerge as one and dwell as one, never quitting each other or leaving each other. Hence it is written, “And a river went out of Eden” (Bereshit 2:10). “Went out” means constantly, never stopping. This is the meaning of the words, “like a spring of water, whose waters fail not” (Yeshayahu 58:11), and the words, “my beloved” referring to Ima; for they dwell in the goodwill of brotherhood and love, in complete unity. But here, in Malchut, she is called a bride. When the male, Zeir Anpin, approaches her to unite with her, she is a bride; that is, her ten Sfirot are rebuilt anew with brains and Netzach, Hod and Yesod for each coupling, because she comes a very bride.
