What is the main symbol for Hinduism called?

One of the main symbols for Hinduism is called "Aum" or "om." It represents a sound that is sacred in the religion.

The sound is sacred because it reflects the one that created the universe. The three syllables in the word "aum" are symbolic of other important threes in the universe, such as Earth, heaven and the atmosphere or the three main deities in Hinduism, Brahma, Shiva and Vishnu. The word also represents the three states of consciousness, waking, dreaming and deep sleeping, with the symbol representing another state, the state of spiritual awareness. In Hinduism, it is used as a chant, a way of meditating.
