Similarly, the Torah as a whole is regarded as the mystical meaning of the structure of man, which is the mystical meaning of the 248 positive mitzvot, which correspond to the 248 limbs, and the 365 negative mitzvot, corresponding to the 365 sinews. It contains five parts, which are the mystical meaning of the five books of the Torah. This is called “the image of the chariot of the supernal man,” i.e., the man of Beria, which is Bina, from where these vessels begin to be drawn in the place of the souls.
He is called “upper man” because there are three levels of man in the sefirot, namely man of Beria, man of Yetzira, and man of Asiya. However, in Keter and Ḥokhma there is no image at all that could be denoted by some letter or dot, or by the four letters of Havaya, as stated. Since here the Zohar is speaking of the world of Beria, it is being precise when it states “supernal man.”53In other words, since there are three levels of man, one in each of the levels of Beria, Yetzira and Asiya, the highest, or "upper" man refers to the level of Beria.
Above that level, in Atzilut and beyond, there is no structure of any kind, as the author of the Sulam explained in the previous sections.
