Rabbi Elazar asks Rabbi Shimon, his father, about how to recognize a proper unification so they won’t make mistakes.
Rabbi Shimon quotes the sages of the Talmud describing the work of the priest when handling the sacrifices.
“עלה בכבש של המזבח ופנה ימינה לסובב ושם היה מהלך לכיוון מזרח, וכך בא לו תחילה לקרן דרומית מזרחית ”
“He (the priest) climbed the ramp of the altar and turned right to turn, and there he walked eastward, and so he came first to the south-east corner”
With this quote rabbi Shimon emphasis that the we should follow the ‘right’ turn that is the Right column and start from the south that is Chessed. Before doing anything one must accepts the Torah as the spiritual laws to follow in the world.
Rabbi Shimon continues to explain that the corner is the aspect of Malchut and that is where we accept the ‘yoke’ of Torah. Then ‘south-east’ to connect the ‘south’, Chessed to the ‘east’ that is the Central column, Tiferet and the Tree of Life. When Chessed is unified in Tiferet, Chokmah is revealed because the central column is the ‘son’, Zeir Anpin. The root of Tiferet is in Da’at that is created by the Father, Chokmah and the Mother that is Binah. For that reason, the unification is at South-East, to strengthen the South, Chessed.
The Zohar gives us here great guide on how to make our prayers and meditations effective. The Torah laws are actual spiritual technology that allow us to draw the Light from its source.
