Zayin (ז) means "sword" or "weapon," symbolizing both the power to cut through illusion and the nourishment that sustains life (as in the word "mazon," food). Its shape resembles a crowned Vav, indicating that spirit (Vav) crowned with consciousness can discern truth from falsehood. The metaphysical meaning of Zayin involves spiritual warfare, meditation, and the ability to use the "sword of truth" to achieve victory over our inner darkness on the path to self-knowledge.
