Om is the most comprehensive and sublime symbol in Hindu metaphysics and was first used in the Upanishads. Om later became the object of mystical meditation as the combination of the three sounds a, u and m. Among other things, it symbolizes the triad of Vishnu, Shiva and Brahma. It corresponds to the states of waking, dreaming, deep sleep and deepest calm. In all Hindu religions it is considered the most sacred of all mantras. (Source: Wikipedia)
