The Om symbol is a sacred sound and spiritual icon in Hinduism, Buddhism, and Jainism. It represents the essence of the ultimate reality, consciousness, and the universe. The symbol is often chanted during meditation and rituals, believed to connect practitioners with the divine. Visually, the Om symbol consists of three curves, a semicircle, and a dot, each representing different states of consciousness: waking, dreaming, and deep sleep. The sound of "Om" is considered a primordial sound, embodying the vibration of the universe and promoting peace and harmony.
