When we read TES (The Study of the Ten Sefirot), we discuss and clarify meanings that are closer to us, in order to prepare ourselves to understand it. But then we have to read the original, authentic text written by great Kabbalists who channel the upper Light to us.
I don’t possess such upper Light as Rabash and Baal HaSulam do, but I can help you connect to it. In order to teach a child, one doesn’t have to be a professor but just someone who can come down to the child’s level.
Therefore, next to the pupil there is a teacher, the most important person who can help him right now. But besides, there are authentic sources which are very precious to us from which the Light comes down to us. It is impossible to get by without one or the other.
On your own, without such a special person as the teacher, you would never be able to attune yourself to the spiritual source of Rabash or Baal HaSulam. And so it was throughout all generations. We don’t speak about such unique souls as Adam HaRishon and Abraham who discovered the spiritual world on their own. Sometimes, there are moments in life when something gets revealed to a person from Above, for some special predestination of the soul.
But if we speak of Kabbalah as the passing of spiritual knowledge through the chain of Kabbalists from generation to generation (“Kabbalah” means “receiving”), then we always imply a teacher and a disciple. Above everything else, the teacher aims you at the goal; he helps you to get around and gives you direction in life. And its realization is definitely your responsibility—with the help of the great Kabbalists who wrote these holy authentic sources for us.
On one hand, there is a teacher who supports and guides you, and that is why you ought to be loyal to him so that he may “hold you in his arms” like a baby. On the other, you walk along his side in order to connect to the authentic sources.
