When an ordinary person studies the writings of the Kabbalists, he learns about what was formerly hidden from him. Only after acquiring the sixth sense through study does he begin to feel and see what was previously unrevealed.

Everyone has a natural ability to develop this sixth sense, and that is the reason Kabbalists transmit their knowledge of the structure of the upper, spiritual world. [See the chapter on “Sensing Reality Through Kabbalah.”]

When a person is exposed to Kabbalistic materials, he may not at first grasp what he is reading. But if he wants to understand, and tries to do so in the proper manner, he invokes what is called the Surrounding Light, the light that corrects him; and very gradually he is shown his spiritual reality. The terms “to correct” and “correction” are used in Kabbalah to describe a change in the desire to receive, i.e., to acquire the qualities of the spiritual world and of the Creator.

Everyone has this sixth, still-dormant spiritual sense; this is called the point of the heart. Opposite it stands the light, which will eventually fill the point, the sixth sense, when it develops.

The sixth sense is also called the spiritual Vessel (Kli), and it continues to exist even without material reality. The spiritual Vessel of the ordinary person who has never studied Kabbalah is not sufficiently developed to feel the spiritual world. When he studies the original Kabbalah writings in the proper way, this light enlightens the point of the heart and begins to develop it. The point then begins to widen and it expands sufficiently to allow the Surrounding Light to enter it. When the light enters into the point of the heart, it gives a person a spiritual feeling. This point is the person’s soul.

Nothing is possible without help from the upper world, without the Surrounding Light descending from above and gradually lighting the way for a person. Even when we do not recognize this light, there is a direct connection between the point of the heart and the light due to fill it, as planned from above. Studying Kabbalah books enables a person to connect to the source of the light, and gradually come to feel a desire for spirituality. This process is called segula (remedy).

Rabbi Yehuda Ashlag wrote in the Introduction to the Study of the Ten Sefirot:

Accordingly, why did the Kabbalists instruct everyone to study Kabbalah? While it is great and worthwhile publicizing that there is an incomparably wonderful quality to studying Kabbalah wisdom, even though they do not know what they are studying, it is the tremendous desire to understand what they are studying that awakens the lights surrounding their soul. That means that every person is assured the possibility of eventually attaining all the wonderful achievements the Creator intended for us in planning Creation. Those who do not attain them in this incarnation will do so in another, until the Creator’s intention is fulfilled. Even if a person does not achieve this completion, the lights are destined to be his; the Surrounding Lights wait for him to prepare his Vessel to receive them. Therefore, even when he lacks the Vessels, when a person is engaged in this wisdom and recalls the names of the lights and Vessels waiting and belonging to him, they will shine on him but only to a certain degree. But they will not penetrate his inner soul, since his Vessels are not yet ready to accept them. Kabbalah is the only means to create the Vessel to receive the light of the Creator. The light he receives when he is engaged in the wisdom imparts to him a grace from above, bestowing an abundance of holiness and purity on him, bringing him closer to reaching completion.

Kabbalah is special in that it gives a person a taste of spirituality while he is studying, and from that experience he comes to prefer spirituality to materialism. In proportion to his spirituality, he clarifies his will and learns to distance himself from things he was once attracted to, much as an adult is no longer attracted to childish games.

Why do we need Kabbalah? Because Kabbalah is given to us as a springboard for change. It is given to us so that we can know and perceive the Creator at any given moment throughout the day. These are the only reasons why the wisdom of Kabbalah was provided. Whoever learns Kabbalah in order to alter himself and improve himself, in order to know the Creator, reaches the stage in which he begins to see he can improve, and fulfill his true destiny in this lifetime.
