Introduction to the Preface to the Wisdom of Kabbalah

1) It is written in The Zohar, Vayikra, Parashat Tazria, p 40, “Come and see, all that exists in the world, exists for man, and everything exists for him, as it is written, ‘Then the Lord God formed man,’ with a full name, as we have established, that he is the whole of everything and contains everything, and all that is Above and below, etc., is included in that image.”

Thus, it explains that all the worlds, Upper and lower, are included in man. And also, the whole of reality within those worlds is only for man.
