Answer: Kabbalists write about the Creator’s revelation as the only necessary action in our world in order to prepare us for it. For this, we need to receive an impression from the Light of Hochma (Wisdom) and the Light of Hassadim (Mercy) and thus form the impressions (Reshimot, spiritual reminiscences) of these influences in our matter (desire) which neither feels nor perceives the spiritual world.
For every influence of the Light, we need to evaluate who receives pleasure from the revelation (reception): I, the Creator, or both? This is why the Light comes from the system of Aba ve Ima (father and mother) while Zeir Anpin (HaVaYaH) operates as the reference point for Malchut, determining what she needs to become in order to become like Him, to receive and bestow Light.
The influence from Above constantly changes Zeir Anpin’s attitude toward Malchut as if he were turning his different sides to her and, this way, she changes. She needs to feel the sensations from Zeir Anpin while the only thing needed from her is her readiness to become like Him.
This is our work because we make up the body of Malchut. Zeir Anpin, on the other hand, teaches us to properly perceive the Light or the three lines by influencing Malchut. He shapes us like a child by filling us with impressions and explanations: the impressions in an obvious manner while the explanations in a concealed manner as if they manifest on their own within us and do not come from Him.
We learn how Malchut is being developed from Above in the Study of the Ten Sefirot. We study how Zeir Anpin prepares Malchut (Nukva) for adhesion with Him in their absolute similarity and absolute opposition.
