Answer: In ancient times, it was not about one Kabbalist or another, but about a whole period of development: the era of Abraham, Isaac, Jacob, Joseph, Moses, and Joshua…Those are periods, rather than people as such. The spirit of the person was active in that time and made what it did. For example, Moses built the nation and contributed the methodology of correction to the desires that were unveiling at that time. As a result, he brought the nation to the Land of Israel, that is, to the revelation of the Creator.
Everything is carried out by the Kabbalists, although we cannot see it during the exile. Kabbalists are the ones by whom the world is being “charged,” which allows it to exist. Without a sparkle of Light, this world would never have appeared in the first place and matter could not have existed. There always are the Kabbalists who, according to their Kelim, belong to the generality of humanity as well as to a spiritual degree.
It is said that “the tail of the lion,” the nine lower Sefirot of the world of Atzilut, together with the Light of Hochma descend to the worlds of BYA and become “the head of the fox” (shualim), in other words, those who ask questions (shoalim). After all, that’s where the broken vessels are located, and so, the question arises: How do we correct them?
We need this connection as well as a permanent opportunity to transition between the levels. In this world, it is ensured by the Kabbalists. On one hand, they are dressed the same as others so that they can teach us. On the other hand, they are a part of a higher degree. There is no other way to achieve this because we are a part of the general system that lives in accordance with rigid laws.
Returning to the question:. After a long exile, Jewish people listened to the advice of the great Kabbalists during the time of Baal Shem Tov and his disciples. They led the nation, guided it forward, and gave birth to generations who lived in accordance with spiritual attainment—to people who connected “the ground” of this world with the height of Ein Sof (Infinity). It was a period of great Kabbalists who were operating in both worlds at the same time.
As to the severe detachment (interruption) of the spiritual connection that was created within the last one hundred years, it is probably something that was supposed to happen. The situation is really critical at this time. And yet, it is said: “I have not forsaken Israel.” Even today, there are Kabbalists who convey illumination from the spiritual world to ours.
Our world is a tiny dark spot in the center of spiritual universe. It is essential to bring the Light into it, otherwise it won’t be able to endure. Throughout all the worlds, the Light descends directly to this plane, to our corrupt desires, and Kabbalists are the ones who safeguard this ray of Light.
You call them “people,” although it has nothing to do with a body, but rather it is about certain desires or states (Kelim). They act deliberately, so that they can descend even lower and be closer to us. For example, Baal HaSulam asked to be lowered in order to be able to write and help those living below.
