Kabbalah is often associated with tradition and even with religion. In most cases, this is a result of the difficulty in finding logic in the old customs and the various prohibitions in the Mitzvot (commandments). It is a difficulty expressed directly or indirectly by antagonism toward religion. This is the reason for the important need to clearly distinguish between Kabbalah and religion.
Every religion relies on a certain prophet, a person who was connected with spirituality and circulated his knowledge among people. This argument is at the basis of every religion, meaning that everything begins with the sublime truth, the revelation of the Creator before the prophet, who was the founder, be it Judaism or any other religion.
The wisdom of Kabbalah is a method to attain the Creator that is available for all. It allows any person to come without any mediators and to reach a spiritual contact with the Creator. People who have reached spiritual attainment described how they did this step by step so that others might follow them to a similar conclusion. One's spiritual connection with the Creator is based on one's own discovery of Him.
Thought the wisdom of Kabbalah does not deal directly with studying this world, it is still the basis of every science in our world. The study of Kabbalah gives one the ability to see how spiritual forces find their expression in this world, how they climb up and down, to and from our world with a variety of forms we call, "phenomena" and physical, chemical, and biological processes, as well as moral and other processes.
Because we are unable to learn all those processes as one collective, we study them as separate, specific sciences. Nevertheless, everything is connected and dependent on every other force and element of nature. After all, the subject matter is one, and we just separate the research into pieces to make it easier on us.
The wisdom of Kabbalah ties all these phenomena of spirit and matter together. This means that from the point of view of Kabbalah, music, astronomy, biology, and medicine externally express a unique law of the inner makings of nature. A Kabbalist who feels the Upper World finds that there is only one law, expressed in many different ways in our world.
The wisdom of Kabbalah contains every necessary component of every science: it consists of researches, records of the results of experiments, continuity and consistency, repetition of the experiments, and accumulation of data. It is a science that deals with the study of the universe, the study of the reality we live in. It is a science that studies nature's only law. Today, we are capable of perceiving only a negligible part of the collective law of reality in the degree of our world. We call that negligible part, "this world."
