Baal HaSulam, article “A Speech for the Completion of The Zohar”: And because The Zohar is revealed in our generation, this is a clear proof that we are now in the time of the Messiah, at the beginning of this generation, about which it is said: “ And the earth will be full of the knowledge of the Creator.”
Baal HaSulam is writing it that because everything is realized by the upper Light. And when the Light is illuminating less, then the nation of Israel is in exile, if it illuminates even less, then we all are in troubles up to the loss of life, meaning losing this perception of reality. And conversely, when the Light illuminates more, then we feel vitality and we live a full life. When it illuminates even more, then we begin to feel the source of the Light and we are attracted to it.
Everything comes from the Light, and precisely it “shakes” the vessels, our desires, but in our era, its bestowing is changing. The revelation of the wisdom of Kabbalah, the thought of creation and its goal, the systems that humanity exists in, the global nature with its absolute laws, which is the Creator, all this brought great changes in our world. In the last century, the Light influenced the world in such a way, that as a result, The Book of Zohar was revealed, meaning that the strongest source of correction was revealed. The authors of The Zohar wrote openly that thanks to this Book, the people of Israel go out of exile. Therefore, it is necessary to see our time as time of spiritual ascent, and everything depends only on the correct use of the wisdom of Kabbalah.
From above there will be no concessions on what we are capable of realizing. But this way or that way, the revealing of The Book of Zohar and the wisdom of Kabbalah, the work that was done by Baal HaSulam that revealed the method of Kabbalah to this generation, and the works of Rabash that describe the rules of spiritual work—all this laid a foundation for our ascent. The two parts of the wisdom of Kabbalah that were prepared by our teachers were necessarily revealed in order for anyone who is awakened to self-realization in the path to the goal of creation (purpose) to be able to execute it.
Therefore, our time is the beginning of the period of the Messiah, meaning the stage of the final correction.
