What are the three parts of the Hindu symbol called?

The Hindu symbol, often referred to as the "Om" or "Aum" symbol, consists of three parts that represent different aspects of the universe. These parts are "A" (representing the waking state), "U" (symbolizing the dream state), and "M" (denoting the state of deep sleep). Together, they encapsulate the essence of the ultimate reality, consciousness, and the cycle of life. The symbol is also associated with the divine trinity of Brahma, Vishnu, and Shiva.
