It is impossible for anyone to calculate the measure of work that he needs to invest in order to move to the next stage. It is impossible to say about an ordinary person, who meanwhile is living his normal corporeal life like everyone else, how many corrections he will need in order for the point in the heart to open in him, the spiritual spark. Also it is impossible to say how many actions he will need to make with this spark in order to reach the first revelation, meaning to connect it with the other sparks.
In the first degree we are connecting our suffering, and then in this measurement of suffering that was connected, finally the spiritual spark is revealed, meaning, a valuable question is reveled in a man: What is the meaning of my life? This spark directs him to the goal, to the answer for the question, “What is the meaning of life.”
After that, he again begins to work in the group that changes him, because he is not able to change by himself. Man finds himself under the influence of the environment and he changes, because it changes. So in the period of preparation, he tries to put himself under the influence of the environment in the most beneficial way for the fastest progress to transfer from the path of suffering to the path of Light, the Torah, the wisdom of Kabbalah.
With that ends the preparation period: preparation for the covenant of self-annulment for Arvut (Mutual Guarantee), rising above the thoughts and disturbances in order to achieve connection of our sparks.
The whole work is done through the influence of the environment upon a man. Therefore, it is impossible to calculate in advance the toil that is demanded from him and the precise situation or state that needs to happen so he will receive the revelation. This is because the revelation depends on the state surrounding him. This state is not coincidental, but to calculate it one needs to know and take into consideration the whole system, and this is impossible from our degree.
From a higher degree it is possible somehow to calculate it, but here there is an additional condition. Each degree includes four phases, a whole HaVaYaH, and in order to rise to the pure calculation, one needs to raise the HaVaYaH. That is, only from the world of Yetzira, one can observe the world of Assiya. And if one exists in a high degree of the world Assiya, it is impossible to calculate what will happen in a lower degree of the same world, because your corrections in the degree of this world (in the Light of the Nefesh) is still not determined.
But due to a man strengthening his connection with the environment, he progresses. Finally, the concealment disappears and he comes to revelation.
Baal HaSulam writes in the “Introduction to the Study of the Ten Sefirot” Letter 54: It is true that after the Creator sees that a man completed the measurement of his work and finished everything that he had to do in his power of choice and strengthening in the Emuna (faith) in the Creator. It means that he proved that he yearns for the quality of bestowal that is called Emuna. And then the Creator helps him and he is rewarded with the attainment of the revealed Providence, it means the revelation of the face.
This help from the Creator cannot come before he finishes his measure of work. It is worthwhile to remember this always, so as not to request revelation, that is, one needs to request from the Creator help to complete the work and not for the revelation. This is a result of our work. A corrected Kli (desire) is felt as the revelation of the upper world. The revelation does not come from someplace outside the man himself, by becoming corrected from not being corrected, by finishing his correction, in this state that until a moment ago was not corrected, suddenly he feels the corrected state that is called redemption.
