The Vav of the name YHVH is the conduit of the supernal light to the lower levels. It is the River that comes out of Eden. Genesis 2:10 “and a river comes out of Eden to water the garden…” Eden and the spring are Chokmah and Binah. The river is the Vav connecting from Binah to the Torah with 53 portions. 53 = גן = Garden, which is the outlet of the Energy to the world. With every reading of the Shabbat portion the world enjoys a fresh new energy that sustains it until the next Shabbat. If God forbid, there won’t be a reading on Shabbat, the world would fall into darkness and cease to exists.
