Every Zoroastrian woman or man wears in the vest a cord of silk, and considers it the most sacred thing for its religious significance. This is the custom that has been observed by Zoroastrians from the beginning of their religion, as Zarathustra himself wore this sacred thread, and it is seen till now with Parsis -- those that have left Persia, their original land, for ages, and have adopted mostly the customs of India, the land where they took refuge after leaving their country, where a Brahman wears a thread crossways over one shoulder.
