If someone promises you a simple book on Kabbalah, then know that this is deception and profanity. The book about the secret Jewish teaching cannot be simple. Nevertheless, we have made every effort to ensure that the book that you are now holding in your hands becomes as understandable as possible even for an unprepared reader. It tells not only about the ancient doctrine that existed two thousand, or a thousand, or at least two hundred years ago, but about a living spiritual tradition that has survived to this day, and it is addressed to everyone who is seriously interested in such an important part of the world spiritual tradition as Kabbalah. Without distinction of gender, age and nationality.
