Om or Aum or Ohm is a term given to the mythical sound of creation.The syllable aum is first described as an all-encompassing mystical entity in the Upanishads and describes that which cannot be described or named but which is the source of all existence. This word has nothing to do with lord Voldemort.
It also refers to the imaginary homeland many anglo indians refer to when they speak of going "home". This om is supposed to lie somewhere between India and England and has never been found. Many Dingos claim to have found it in New Zealand, America, Australia and even the UK but they aren't really being truthful.
