Baal HaSulam, “Introduction to The Book of Zohar,” Section 63: ….this is the rule in all the Partzufim (plural for Partzuf) of the worlds and of the souls, that the purer one is the first to be selected into the Partzuf. Therefore, the purer Kelim, HBD, were selected first in the world and in the souls.
Thus, the souls in the first two millennia were much Higher. Yet, they could not receive the full measure of Light, due to the lack of the lower parts in the world and in themselves, which are HGT NHYM.
Baal HaSulam explains the gradual decline in the generations, as a result of it, our generation is the lowest and has sunk to the bottom.
Today we don’t know where we came from, where we are going and why. We don’t know our root or our purpose, or what we need to do in our lives. We have no connection with the sources; essentially we have no concept of what the Torah and Mitzvot are in their true and inner sense.
For what and why we are alive? What is the reason for our lives? All this is unknown to us. There are no longer any of the great Kabbalists who could lead us as shepherds, guides. But the main thing is that the connection with the source, with the foundations of the nation, is lost; it has disappeared. And therefore, we are found in total darkness.
It’s not by accident that we find ourselves in this darkness. This is because the revelation of the Creator to the creature, from beginning to end, is divided into six thousand levels that are called the “six thousand years.”
We begin to count these levels from the first revelation of the Creator to the creature, who is called, Adam HaRishon. This was the first human who discovered the Creator; this was the first Reshimo to be realized, meaning that he corrected himself. And further, from him until the last Reshimo that must correct itself, six thousand levels must be traversed which are divided into three periods of two-thousand years each: HBD, HGT, NHY.
From this it’s understandable to us that the decline of the generations is not derived from anyone’s fault. From the start, we had to descend to the present state, until our present life. And precisely from this wretched life, from the deep abyss, we can begin the ascent to the summit. Then we will understand how great the difference is between the vessel and the Light, and thanks to this we can truly appreciate the Creator.
