Hari or Har is a name for the supreme absolute in the Vedas. Hari refers to God who takes away all the sorrows of his devotees. In the Rigveda’sPurusha Suktam, Hari is the first and most important name of God, second and alternative name of the supreme Being is Narayana according to Narayana Suktam of theYajurveda. Within the Hindutradition, it is often used interchangeably with Vishnu to such an extent that they are considered to be one and the same. In the Vedas, it is required to use the mantra "Harih om" before any recitation, just to declare that every ritual we perform is an offering to that supreme Divine Being; even if the hymn praises some one or the other demigods. The idea of demigods as found in Hinduism is very different from that found within Greco-Roman mythology. This has to be borne in mind while understanding how, within Hinduism, all beings including demigods are inseparable from Hari. The phrase "Harih Om" gestures towards Advaita Vedanta and other categories of non-dual thinking. "Harih Om" is akin to saying that all creation that we can see is in fact, a mirroring of the One Self. This is not the concept of mimesis as found in Western philosophy. In Hinduism, kirtan or praise songs of any demigod has a common name known as Hari kirtan and katha and, storytelling is known as Hari katha. No depiction of Hari is permitted in Sikhism. Hari in Purusha Suktam, Narayana Suktam and Rudra Suktam is usually depicted as having a form with countless heads, limbs and arms. Lord Hari is also called sharangapani as he also wields a bow named as sharanga. The word "Hari" is widely used in Sanskrit and Prakrit literature as well as in Hindu, Sikhism, Buddhist and Jain religions. The name "Hari" also appears as the 656th name of Vishnu in the Vishnu sahasranama of the Mahabharata and is considered to be of great significance in Vaishnavism.
