The Zohar, Chapter “Song of Songs,” Item 482: The wisdom that one should know: to know and to observe the secret of his Master, to know himself, to know who he is, how he was created, where he comes from and where he is going, how the body is corrected, and how he will be judged by the King of All.
We think of these merely as pretty words: “where he comes from and where he is going,” and “how he will be judged by the King of All.” However, the most important part is, “to know and to observe the secret of his Master.” This is exactly what we must attain.
The Creator wants us to reveal His entire work, His entire creation, the entire reality He created, the reasons for its creation, the thought of creation, the ways to realize it, and the goal that the entire creation is to reach. The only way to learn all this is by attaining it, which means, basically, to clothe into the entire creation with all of its states and experience all of them. Only then, by including our actions in the entire creation, can we attain it in us or in our desires (Kelim). From this attainment, we will reach everything that we need to reach.
We can attain this by correcting our desires. These desires are given to us from Above and they are corrected by the Upper Light. However, the Light only appears according to our readiness, our efforts, and our desire for the Light to come and correct us. This is called the raising of MAN. Man must strive to reach a state when he desires the Light to correct him.
