We have been evolving over thousands of years, and at a certain point, we start awakening to questions about the meaning and purpose of our lives.
Kabbalah is an ancient wisdom that has been hidden for thousands of years and was waiting for the perfect time to be revealed to humanity. That time is now.
According to the great Kabbalist, the Ari (Rav Isaac Luria), the question about the meaning and purpose of life started emerging in humanity as a whole toward the end of the Middle Ages and the beginning of the Renaissance. This is why he stated that from his time, the wisdom of Kabbalah was open to all.
At the start of the “Introduction to The Study of the Ten Sefirot,” Kabbalist Yehuda Ashlag (Baal HaSulam) wrote:
“Indeed, if we set our hearts to answer but one very famous question, I am certain that all these questions and doubts as to whether we should study the wisdom of Kabbalah will vanish from the horizon, and you will look unto their place to find them gone. This indignant question is a question that the whole world asks, namely, ‘What is the meaning of my life?’”
