Baal HaSulam, “The Teaching of the Kabbalah and Its Essence”: Clearly, when one ponders and contemplates words of the Torah that pertain to the revelation of the Creator to our fathers, they bring the examiner more Light than when examining practical matters.
This is how Baal HaSulam recommends we read books that tell us about the relationship between a human being and the revelation. The articles, letters, The Study of the Ten Sefirot, and the Sulam commentary to The Book of Zohar, in fact everything we received from Baal HaSulam and Rabash are books that are especially for us about the revelation of the Creator to the created being. They are written in different styles but they are all about this.
Some of them explain things directly and describe the spiritual work psychologically, so to speak, like the letters and the articles. In other articles we read about the connection between the wisdom of Kabbalah and other sciences, but they are also about the revelation of the Creator to a person. We see this especially in works talking about The Book of Zohar and in The Study of the Ten Sefirot.
All these books and texts were written during the drawing of the Light. Kabbalists discovered the Light in different states and levels and wrote accordingly. There isn’t one word or one letter that was written before the writer had attained the specific state that he described in the text.
So when we read these texts, we can receive the power in them. It is by these texts that we connect to the writers, and then we can draw and enjoy the Light that Reforms, but this is only if we yearn to resemble them in their simple faith and receive everything that they have. While reading his writings, I want to be like the Kabbalist, to annul myself, to belong to him, and by that I turn on the Light that he has prepared for me.
