Aum (also Om) "to sound out loudly" or ("om; syllable") is a mystical or sacred syllable in the Indian religions which originated from Hinduism.
The concept of om, is found in Sikh theology as a symbol of God. It invariably emphasizes God's singularity, expressed as Ek Onkar ("One Omkara" or "The Aum is One"), stating that the multiplicity of existence symbolized in the aum syllable is really founded in a singular God.
