Om also written as 'Aum', is the most sacred syllable, symbol, or mantra in Hinduism, that signifies the essence of the ultimate reality, consciousness. The Om sound is the primordial sound, and is called the Shabda-Brahman. It is a syllable that is chanted either independently or before a mantra. It is also found in Jainism, Buddhism, and Sikhism.
The syllable Om is also referred to as onkara (ओङ्कार, oṅkāra), omkara (ओंकार, oṃkāra), and pranava (प्रणव, praṇava).
Om is part of the iconography found in ancient and medieval era manuscripts, temples, monasteries and spiritual retreats in Hinduism, Buddhism, and Jainism. The symbol has a spiritual meaning in all Indian dharmas, but the meaning and connotations of Om vary between the diverse schools within and across the various traditions.
In Hinduism, Om is one of the most important spiritual sounds. It refers to Atman (soul, self within) and Brahman (ultimate reality, entirety of the universe, truth, divine, supreme spirit, cosmic principles, knowledge). The syllable is often found at the beginning and the end of chapters in the Vedas, the Upanishads, and other Hindu texts. It is a sacred spiritual incantation made before and during the recitation of spiritual texts, during puja and private prayers, in ceremonies of rites of passages (sanskara) such as weddings, and sometimes during meditative and spiritual activities such as Yoga.
