"Aum," often spelled "Om," is a sacred sound and spiritual symbol in Hinduism, Buddhism, and Jainism. It represents the essence of the ultimate reality or consciousness. The sound is composed of three syllables: "A," "U," and "M," which symbolize various states of existence, including creation, preservation, and destruction. In meditation and spiritual practices, chanting "Aum" is believed to help practitioners connect with their inner selves and the universe. It is often used at the beginning and end of prayers or meditation sessions, serving as a reminder of the interconnectedness of all life and the importance of mindfulness.
