“God spoke to Moses, telling him to speak to Aaron and say to him, 'When you light the lamps, the seven lamps shall illuminate the menorah.'”
The subject of the Menorah was started in the portion of Tetzaveh. There we said that the Menorah represents the Cosmic Female, and explained the meaning of the beating of the olives to prepare the oil. More specifically, the Menorah represents Rachel. This means that the spiritual qualities of the world that were embodied by the Matriarch Rachel, were later found in the Menorah. Rachel is the Female companion of the Cosmic Man, who is also called Zeir Anpin (Small Face).
At earlier times, the Cosmic Man and his Female were standing face to face with each other. Then the Menorah was not needed. However, later the Cosmic Female and the Cosmic Man stood back to back to each other, because they were afraid of the Evil Husks who would attack the Female. The Menorah in the time of the Temple rectified the situation.
The seven branches of the Menorah represent the lower seven Sefirot (God's manifestations in the world) of the Female, from Kindness to Rulership. They are arranged in groups of right (Mercy), left ( Judgment), and center (Beauty, or balance and proportionality). The branches are endowed with the five aspects of Strength, characteristic of the Female, who limits and shapes the world.
The five attributes of Kindness from the Mind of the Cosmic Man likewise descend to his seven Sefirot, and are manifest in the lights of the Menorah. The seven lights, with their fire and flame, coming from the wick, represents the seven qualities of the Cosmic Man.
Today, when there is no Menorah, the union can still be accomplished by the Cosmic Man and his Female ascending to their supernal Mother and Father, who shade and protect them for the time of their visit. Those who know do this in the prayer, through a “unification” mediation in Shema and in the Tachanun, where they enact the actions of the spiritual entities (Partzufim) mentioned above.
