Answer: No, it isn’t. Since all the souls are connected, a single soul (degree) can’t complete its correction without correcting the parts of the next degree. No person lives for his own sake; the whole system is a system of mutual bestowal.
Therefore, it is impossible for someone to correct himself for his own sake. Everyone lives in order to provide correction and fulfillment for others. It is impossible for a soul that corrects itself not to have a part which was corrected for it by the predecessors and a part that it must correct for others.
We know that the upper part of every soul, its GE (Galgalta ve Eynaim), exists in the lower part, the AHP (Awzen, Hotem, Peh), of the preceding, higher soul (Partzuf). The soul’s lower part, its AHP, is situated in the GE of the the lower soul.
Thus, our free choice is in the place where we are not connected to a higher or a lower soul; it is in the middle part of our soul, the middle part of the Sefira Tifferet. A free space from all souls is formed there; it is our freedom of will. In essence, it represents a special unification in our soul of the higher and lower souls. In this unification, they are equal, and, thus, they give us freedom of choice.
Outside of the middle part of Sefira Tifferet, the parts of the soul do not belong to the soul itself. The upper part pertains to the higher soul (the previous Partzuf), and the lower part pertains to the lower soul, its “successor.”
Therefore, a calculation is always performed on bestowal to the upper one and the lower one. The decision about this bestowal is made in the middle; there is no other freedom. This middle point arose artificially through the unification of Bina and Malchut. It is called Klipat Noga, and it constitutes my point of choice. Besides this point, everything else belongs not to me, but to the upper or lower Partzufim (plural of Partzuf) relative to me. I am situated in the middle, and I constantly need to decide how I am connected to them.
However, this point that makes the decision is, in fact, the “I” or “human being,” the one who is “similar” to the Creator. On one side, there is Malchut, and, on the other, there is Bina. Thus, there is a special contact of Bina and Malchut (the qualities of the Creator and the creature) at this point. This contact yields a free decision to make the creature similar to the Creator. It is called “Adam” or “similar.”
Until we reach this decision, we are not “human.” The human begins from 1) realization of the difference between Bina and Malchut, and 2) the connection between them. The human being grows from this point to the extent that he is able to serve others with his 613 desires: the upper ones with his 248 desires and the lower ones with his 365 desires.
If you don’t do this, you remain only a point. Yet, if you do, you develop your Galgalta ve Eynaim, and they spread out onto the common Soul: all the souls that are higher and lower than you.
