Om or Aum is a sacred sound of a spiritual symbol in Indian religions. It signifies the essence of the ultimate reality, consciousness or Atman. More broadly, it is a syllable that is chanted either independently or before a spiritual recitation in Hinduism, Buddhism, and Jainism. The meaning and connotations of Om vary between the diverse schools within and across the various traditions. It is also part of the iconography found in ancient and medieval era manuscripts, temples, monasteries and spiritual retreats in Hinduism, Buddhism, Jainism and Sikhism.
