The "Rivers" described in this Vision are the four rivers of Eden, the branches of the River that "floweth and faileth not." According to dogmatic Qabalah of western mysticism, the River Naher was described as flowing from the Supernal Eden unto Daath where it divided into four heads, being the rivers Pison (fire) flowing into Geburah, Gihon (water) flowing into Chesed, Hiddikel (air) flowing into Tiphareth, and Phrath (earth) flowing into Malkuth. After the so-called "fall of Adam" Tetragrammaton Elohim placed the four letters IHVH between the devastated Garden and the Supernal Eden. The four rivers formed a Cross upon which the "second Adam" (Jesus) was symbolically crucified.
The rushing together of the Rivers described in the Vision and the Voice predicts the annihilation of the Cross of Suffering (the throne of the Christian Messiah) and the destruction of the name Jehovah which sealed it's establishment. The Cubic Stone against which the name of Jehovah is broken has six sides with twelve lines and eight points, the total of which is twenty-six, the balance of the elements in the Tetragrammaton. But more than this, the Cubic Stone is the Throne of the Emperor.
The Woman of the Star pours the bright dew over herself (Heh final), and into the sand of the accursed Abyss so that the river (Heh prima) gushes forth. She is thus Anima Mundi even as she is the Lady of the Great Sea. A clue to her true identity is offered in the Wake World:
"Then there was another passage which was really too secret for anything; all I shall tell you is, there was the most beautiful Goddess that ever was, and she was washing herself in a river of dew. If you ask her what she is doing, she says: "I'm making thunderbolts." It was only starlight, and yet one could see quite clearly, so I don't think I'm making a mistake."
As revealed in Liber CDXVIII (418), the light of that Star comes from the path of Aleph [and is projected onto the Path of Heh. Aeon418], and Aleph is the Thunderbolt by shape. This is also indicated by Liber CCXXXI, which describes The Star as follows:
"Transformed, the holy virgin appeared as a fluidic fire, making her beauty into a thunderbolt."

In the Aeon of the Child, the Thunderbolt is one of the symbols of Messiah, as it is revealed in the Holy Books:
"Blessed, blessed, blessed; yea, blessed; thrice and four times blessed is he that hath attained to look upon thy face. For I will hurl thee forth from my presence as a whirling thunderbolt to guard the ways, and whom thou smitest shall be smitten indeed. And whom thou lovest shall be loved indeed."
