Question: Why does the weekly section of the Torah, BeHaalotcha begin with the description of the Menorah (lamp)?
Answer: It is because the Menorah (lamp) is the embodiment of the Light that descends from above unto the human souls. It is a Menorah of seven candles that is the embodiment of the six Lights that descend from Above: Hesed, Gevura, Tifferet, Netzach, Hod, and Yesod. All the six Lights belong to Zeir Anpin, a structure that we call the Creator.
The Creator is a relative concept that symbolizes the one who is above us. Because Zeir Anpin is above Malchut it is revealed as the Creator with regard to us. If we ascend to His level, it rises above us once again and so there is a different Creator each time: we change and ascend and He changes and ascends. It is all relative.
The Creator operates and influences us by the seven Lights and so the Menorah is called the lamp of the seven candles (three candles on the right, three on the left and one in the middle), which symbolizes our connection with the Creator. Thus, we change our properties into the opposite attributes, the attributes of receiving into attributes of bestowal, and can illuminate like Him.
Three candles on the right and three on the left symbolize the right and the left lines and we who are in the middle are the middle line in the spiritual work. Of all the items that symbolize different attributes of the connection between the Creator and the created beings, the lamp is the brightest and most prominent symbol of this connection.
