In other words: A person contemplates on the greatness of Hashem, how He has millions of worlds and levels that are all bateil to Him. Then, he contrasts that with the fact that our entire seemingly independent existence is only from Hashem’s attribute of Kingship, through which He hides His Light and the revelation of His Oneness. This contrast will bring a person to an even greater yearning for Hashem than just thinking about Hashem’s greatness. Hashem is so great and I don’t see Hashem at all.
When a person will think deeply into these ideas with the depth of his understanding, so that it should be fully revealed in his mind, and not just knowledge that is “in the back of the mind,” this will produce a revealed love for Hashem in his heart, so that “my soul yearns and longs for Hashem.” (Tehillim 84:3)
With this he will come to actually fulfill the command “you should love Hashem your G-d,” meaning, to actually connect to the Infinite One blessed be He, as it is written “what do I want in heaven or earth besides for Hashem Himself?” (Tehillim 73:25)
