The Dark before the Dawn
From the book Kabbalah for Beginners
The darkest time of night is right before the dawn. Similarly, the writers of The Book of Zohar said, almost 2,000 years ago, that humanity’s darkest time will come right before its spiritual awakening. For centuries, beginning with the Ari, who lived in the 16th century, Kabbalists have been writing that the time The Book of Zohar referred to was the end of the 20th century. They called it “the last generation.”
They did not mean that we would all perish in some apocalyptic, spectacular event. In Kabbalah, a generation represents a spiritual state. The last generation is the last and highest state that can be reached. And Kabbalists said that the time we are living in—the beginning of the 21st century—is when we would see the generation of the spiritual ascent, the last state of our evolution.
But these Kabbalists also said that for this change to happen, we must change the way we are evolving. They said that today, a conscious, voluntary evolution is required, born of our own free choice to grow.
