The only thing we have to correct is our relationship with the upper force that controls everything and manages life, as it says: “There is none else besides Him.” There are four languages that speak about the relationship between man and the upper force: Pshat, Remez, Drush, and Sod (Torah, Mishnah, Talmud, and Kabbalah).
They belong to the four levels of the desire: still, vegetative, animate, and speaking, and accordingly the clarification is in four ways. In this case there is already an opposite division in which the wisdom of Kabbalah is the simple interpretation and not Sod (secret) in which everything is revealed to a person. So we need the language of Kabbalah in order to be sure that we advance correctly.
It is an essential precondition, but it isn’t enough since the wisdom of Kabbalah can be perceived incorrectly. But at least a person learns from the right sources, which provide him with the right approach to the writings, although there are people who try to extract some secrets, mysticism, abstract knowledge, blessings, and remedies.
But still it is very important to stick to the language of Kabbalah and to the Kabbalistic approach and study conditions, since it is different from the ordinary study of different sciences. Here we are totally dependent on the source, which passes us this spiritual knowledge. If the source is real and reliable, we advance gradually according to our exertion and the positive external conditions in order to eventually attain the opening of the eyes.
We study about ourselves and about our nature by starting to feel a little what bestowal is, the force that is opposite from us. Then by the balance of these two forces, the force of receiving and the force of bestowal, we begin to feel the creation. Thus we attain the Creator by His actions upon us.
