Gemara: Sudra (a cloth to cover the head) hints at sod Hashem liyrei’av (the secret of Hashem is [known] to those who fear him).



Ein Ayah: Thoughts are always covered up. Whatever we can figure out based on the person’s speech or action is but the dressing up of the thought, and not the thought itself. The thought, which is the spirit of the related speech and actions, is the foundation of the secret and light behind the thought’s source. A thought of divine origin comes when one has fear of Hashem in such a manner that he can recognize the divine truth, and his actions and speech also are consistent with their thoughts. Although the "clothes" of the thoughts cannot express its full extent, they can at least express their essence to the maximum that can come out.

For this reason, the name used for the head covering of a talmid chacham expresses the point that they have a special honorable head dressing hinting that inside there dwells a hidden soul of deep thoughts. There are great secrets, and there is a delicate expression of the light of holy fear of Hashem, which the sudra hints at.
