The Om sound and symbol have their origins in Hinduism, but they are also common to other religions, including Sikhism, Buddhism, and Jainism. Some scholars claim that the Christian word Amen and the Islamic word Amin come from the word Om as well. No one really knows when the symbol began to be used. The three-part Om symbol represents the three stages universal to all living—birth, life, and death—as well as the three-part unions of body, mind, and spirit and heaven, earth, and the underworld.
When NASA scientists recorded the sounds created by the explosions of the sun, many were struck with the sense that they sounded uncannily like the sound of Om.
Om, in fact, may be the most elemental sound in the universe, and we love sharing this ancient much-revered symbol.
