Therefore, we must ask, Why then did the Kabbalists obligate every person to study the wisdom of Kabbalah? Indeed, there is a great thing about it, which should be publicized: There is a wonderful, invaluable remedy to those who engage in the wisdom of Kabbalah. Although they do not understand what they are learning, through the yearning and the great desire to understand what they are learning, they awaken upon themselves the lights that surround their souls (Baal HaSulam, Introduction to The Study of the Ten Sefirot).
The fact is that Kabbalistic texts speak about the structure of the soul and the structure of the entire system of spiritual forces. By studying them, we awaken these spiritual forces that influence us with greater intensity and develop us with greater speed in the correct direction.
If a person along with everyone in the group reads, say The Book of Zohar, and utters some words he does not understand the meaning of, he still awakens the surrounding light with his desire, which then becomes his inner light.
