We have no chance of attaining the spiritual reality with our egoistic mind. It simply can’t perceive it! Spiritual perception is called attainment (Hasaga), which comes from the saying, “Attainment in the hand,” where the “hand” is the corrected egoistic desire.
This is why there are certain rules in the science of Kabbalah: “From Your actions, I will know You,” “The judge has no more than what his eyes can see,” and so on. These sayings indicate that the Upper World has to be revealed through clear attainment.
We go through 125 degrees of attainment, from the beginning to the end. Each degree consists of 25 individual Partzufim or states (see Baal HaSulam’s “Beit Shaar HaKavanot”). It turns out that each of the 125 degrees, called a “Sefira,” includes 25 of its own forms, and each of those also includes 25 of its own sub-forms, and so on, until Infinity.
This is impossible to calculate. There is no specific number that can designate them. Only on a higher level, where there are no letters or numbers, can we comprehend all of this diversity, because we will have new qualities and a new mind. Then, the number of forms will turn into a higher quality and we will perceive it naturally and simply.
Therefore, an infinite number of Partzufim, Sefirot, worlds or degrees of spiritual attainment, only seems infinite to our current mind. However, for a spiritual mind, everything is reduced to a simple desire for bestowal and love, where we feel adhesion with the Creator as one whole “I, where we, the Light, and the Creator are One!”
