What is Om (Aum) ? Know that Om chanting is NOT a Religious practice. It is a universal syllable. It is a cosmic sound which initiated the creation of the universe. The Om Mantra or “AUM” is the highest sacred symbol in Hinduism. AUM is the representation of the Hindu trinity Brahma, Vishnu and Mahesh. Om is also uttered as ‘A-U-M’. The sound of ‘A’ is guttural, it comes from the back of our throat . ‘U’ proceeds exactly from the middle of the vocal region, the palate . ‘M’ is labial and nasal, which comes from the extremity of the vocal organ or lips. Thus, ‘A’ represents the beginning of the range of sound, ‘U’ represents the middle, and ‘M’ represents the end. It covers the whole field of the vocal organs.
