132. Here is what is written about the Levites: "And thus shall you do to them, to cleanse them: Sprinkle water of purifying on them, and let them shave all their flesh" (Bemidbar 8:7). As soon as they shave their hair and fulfill all this, the Levites are considered pure but not holy. But as soon as the Nazirite isolates from the side OF THE LEFT, he is considered holy and not pure. Thus, it is written: "All the days of his vow of his separation...during which he separates himself to Hashem, he shall be holy" (Bemidbar 6:5).
133. "And shall let the locks of the hair of his head grow" (Ibid.). It is because it is written: "And the hair of whose head was like pure wool" (Daniel 7:9). By this, he is similar to the higher, SINCE HIS HAIR DRAWS CHASSADIM AND WITHOUT JUDGMENT, SINCE HE IS WHOLLY OF THE RIGHT. Rabbi Yehuda ben Rav said: With his hair alone, it is apparent that he is holy, as it is written ABOUT THE HOLY ONE, BLESSED BE HE: "His locks are wavy" (Shir Hashirim 5:11).
134. Rabbi Shimon taught, If people would know what is spoken about this hair and its secret meaning, as it is ABOVE in the utmost secrecy, they would have distinguished themselves to their Master with the highest wisdom. Up to here have been the secrets of the Torah; from now on Sitrei Torah: "And her merchandise and her hire shall be holiness to Hashem" (Yeshayah 23:18).
