There is a physical branch and there is a spiritual root. In spirituality, the “land of Israel” in its complete form is Malchut which rises completely to Bina, and this is not parts of Malchut that we raise to Bina. “Land” is “desire,” and “Israel” is “directly towards the Creator,” (Yashar-El). In this way, a desire that rises to Keter must rise to the level of Bina, thereby correcting itself. Therefore, the land of Israel is called Malchut on the level of Bina which is called the redemption.
When Malchut is entirely on the level of Bina, it begins to receive the Light of Hochma that is revealed within the Light of Hassadim. And this is called redemption, the revelation of the Creator to the creature. Therefore it is said that the revelation of the Creator can only be in the land of Israel.
We must interpret these terms correctly in their spiritual sense. For example, we say: “His glory fills the world”; this is that Malchut rises to a level compatible with the land of Israel.
An additional example: We say that at the end of correction, with the coming of the Messiah, i.e., the Light that draws (Moshech) Malchut to Bina, then the land of Israel is spread throughout the world. In other words, the characteristic of Bina dominates the entire desire to receive and corrects it.
Therefore the redemption, the coming of the Messiah, the revelation of the Creator, and all similar phenomena can exist only in the land of Israel, in the corrected desire.
But there is also a relationship in the material world. After all, every spiritual root must reach the material branch. And therefore anything spiritual cannot happen anywhere except in the land of Israel. And therefore everything will happen around the land of Israel, or in another place, but in connection with it or with the Jewish people. All events, in one way or another, are linked to this, and someday we will see that their cause and their root lies here….
