When the Right joins the middle column that includes the Left, it goes up and connects to the source of the three dots (Yods) of the Cholam, Shuruk, and Chirik as explains previously (#34). Yessod is coming out and holds the middle column and for that is called “כל” “All” that means it holds everything above it. ‘כל’ has the numerical value of 50 to represent the five sefirot above Yessod, which are Hod, Netzach, Tiferet, Gevurah, and Chessed.
The Left is Gevurah that doesn’t reveal light unless it is connected with the Right in the center column. The lack of light creates a ‘burning’ desire that gives it the aspect of a female. The Right side is considered male because it fulfills the desire of the Left for Light and ‘fruition’.
Yessod holds to the center column after the Right and the Left joined to make it. The channel that was created allowed the Light from the Chokmah to nourish the lower worlds of Briah (Creation), Yetzira (Formation) and Asiah (Action), and deliver pure souls of Tzadikim.
The last few studies describe the first stages of forming the flow of light from Keter to Malchut. To study the whole creation process in detail, follow the studies of the Tree of Life that will be posted, hopefully, every week in addition to the regular DZ studies.
