In other words, first a person needs to bring humility to Hashem, which is called “olive oil,” in order to experience the connection to Hashem that is revealed in Torah study through Moshe.
“Olive oil” represents Chochma. This is the ability to see how everything is constantly being created by Hashem and has no separate existence from Him. When one “sees” that in their mind and heart, this will humble their ego and allow them to perceive Hashem’s Light in the Torah.
In the Zohar where this quote is taken from, it says: “There is a mitzvah to love Hashem with great intensity. This is connected to the right hand, (which is Kindness/Love.) One who loves Hashem, he awakens the “Right Hand” of Hashem towards him, and Hashem accepts the person in love. Everything in the world is dependent on a person’s desire, since a spirit of desire from the person draws forth and brings about a spirit of desire from Hashem towards him. We find a similar concept in Iyov (35): “If one will give over his heart to Hashem, then Hashem will gather his spirit and soul to come close to Him.”
The Alter Rebbe is applying this concept to humility. When one humbles himself to Hashem, Hashem will help him achieve true selfless transparency to Him, so he can experience His Light in Torah study.
