This is the place where a person experiences himself and his independence. It is where he has his inner struggle and doubts: what to identify himself with, the upper or the lower? This is called the middle third of Tifferet, the place of free choice.
Question: What is this part made of? And how does freedom of choice become revealed there if this part is influenced by the upper one or the lower one, depending on whom it identifies itself with? Then where is the independence?
Answer: That is how the place of freedom is arranged for a person from Above. This is not confusion or lack of clarity the way freedom in our world refers to the absence of precise knowledge of what to identify yourself with. Rather, in the middle third of Tifferet it is absolutely clear to me what the quality of bestowal is above and what the quality of reception is below. I am in the middle, and this middle is all of me. That is to say, all of my reality is the middle part of Tifferet.
Wherever I am under the influence of the upper one or the lower one, I feel their influence, meaning I feel them and do not relate this to myself. But in the middle third of Tifferet I reveal the full HaVaYaH, myself. This part contains the full ten Sefirot, the discernments of the entire Partzuf.
If I want to attain the upper one, then I ascend to the upper part, and if I want to attain the lower one, then I descend to the lower part. But who am I? This is the middle part of Tifferet, like a thin layer between the upper and the lower. Yet, in reality it is not thin.
The middle third of Tifferet comes from the fact that in the four phases of the expansion of direct Light, Bina decided that it desires not to receive, but to become similar to the upper one, and to do that it has to attain bestowal. However, it cannot attain bestowal because its matter, the will to enjoy, does not change. In order to make it seemingly bestowing, it has to receive for the sake of bestowal. That is, it uses the Giver’s force of love.
Without the force of the Giver’s love for me, I cannot transform my reception to bestowal to Him. But if I know that He loves me and I plan to receive from Him only for that reason, then I use the force of His love. At first I have to reveal His love, and inside of it to reveal my reception, and then to receive from Him only in order to show Him my love.
From the same field where the second phase (of the four phases of the expansion of direct Light) makes the decision, that is where our notion of the middle third of Tifferet is born, in which creation feels free to make decisions.
