Vav (ו) means "hook" or "nail," and its form is a vertical line, symbolizing a channel connecting heaven and earth. It is the power of connection and continuity, often used as a prefix meaning "and," linking all aspects of creation. Vav represents the upright human being and the spinal column in esoteric teachings. Its sacred symbolism teaches us about our role as conscious conduits, drawing down divine light into the physical world to achieve spiritual alignment.
