Answer: It is a tremendous pleasure, because when a Kabbalist reads The Book of Zohar and discovers its meaning, he sees how all the parts of the creation connect above all the differences. The greatest pleasure is when all the parts that seem totally incompatible suddenly become compatible to each other, connect, and merge into one.
Question: Can it be compared to an ordinary person who reads a novel or an adventure book and finds great pleasure in it?
Answer: Yes. After all, as children we received very vivid impressions from reading books, but the pleasure from The Book of Zohar is much more sublime.
Today, when it is already impossible to surprise and to fill us with anything, The Book of Zohar can absolutely fill us. It all depends on its effect on a person.
