28. HE COMPARES THIS SUBJECT MATTER OF ABA AND IMA ABOVE AND YISRAEL-SABA AND TEVUNAH to a spring and source of water that fills up a huge lake. From there, FROM THE LAKE, flow springs, streams and rivers in every direction, TO THE RIGHT AND TO THE LEFT. Similarly, this ABA AND IMA AND YISRAEL-SABA AND TEVUNAH flows through a certain narrow path that is not known, MEANING AT THE UNION OF YESOD'S ABA AND IMA ABOVE, WHO ARE NOT REVEALED, IN WHOM THE YUD DOES NOT EMANATE FROM THE AIR. That river emerges continuously and emanates FROM EDEN. THROUGH THIS EXITING AND ENTERING, it fills that deep stream - MEANING YISRAEL-SABA AND TEVUNAH, SIMILAR TO THE HUGE LAKE OF WATER THAT IS FILLED UP FROM THE SPRING AND SOURCE THAT ARE ABA AND IMA ABOVE. From there, springs and streams continue TO ZEIR ANPIN AND MALCHUT, and from it they are filled up WITH CHOCHMAH AND CHASSADIM. This is what it is written: "He sends the springs into the valleys" (Ibid.). These are the higher sanctified rivers OF ZEIR ANPIN of pure balsam, SINCE IT IS THE SECRET OF THE PURE AIR THAT CHESED, GVURAH AND TIFERET OF ZEIR ANPIN RECEIVE FROM ABA AND IMA ABOVE. THAT IS THE SECRET OF THE PURE BALSAM AND THAT IS WHAT IS MEANT BY: "THEY FLOW BETWEEN THE HILLS," WHICH ARE CHESED, GVURAH AND TIFERET OF ZEIR ANPIN, CALLED 'MOUNTAINS.' AND FROM IT MALCHUT RECEIVES. And all, ZEIR ANPIN AND MALCHUT, drink together from that spring of the higher sanctified stream that continues to flow, WHICH IS YISRAEL-SABA AND TEVUNAH.
