Idra Raba: Chapter 6

Pure wool


Rabbi Shimon talks about the thousands of groups of hairs in the skull of the head, every strand of which glows in 410 worlds. A well spring glows and flows from these strands to the strands of Zeir Anpin, and the brain of Zeir Anpin gets constructed from these, after which it flows to the 32 paths of wisdom. Rabbi Shimon says that a person's character is revealed from his hair. From the parting of the hair Rabbi Shimon deduces a parting into 613 ways of the Torah, meaning the 613 precepts.
