Om

Om or aum (written universally as ॐ; in Devanagari as ओं oṃ, औं auṃ, or ओम् om ) is a mystical Sanskrit sound of Hindu origin, sacred and important in various Dharmic religions such as Hinduism, Buddhism and Jainism. The syllable is also referred to as omkara (ओंकार oṃkāra) or aumkara (औंकार auṃkāra), literally "om syllable", and in Sanskrit it is sometimes referred to as प्रणव (praṇava), literally "that which is sounded out loudly".
