Hari (Devanagari: हरि), the one who forgives all sins, is a primary god in Hinduism and an avatar of Vishnu. The terms "Hari" and "Vishnu" are often used interchangeably. Hari is usually depicted as a pale-blue being, similar to Vishnu's incarnations of Rama and Krishna. He holds a padma (lotus flower) in his lower left hand, the Kaumodaki gada (mace) in his lower right hand, the Panchajanya shankha (conch) in his upper left hand and the discus weapon considered to be the most powerful weapon according to Hindu Religion Sudarshana Chakra in his upper right hand and also have a bow named as sharanga and due to which he is sometimes named as sharangapani (hari) in Bhagvad Gita. Om precedes all else as in Om Namah Shivaya, Om Namo Bhagavate Vasudevaya, Om Namo Narayanaya. But only Hari precedes Om in the form of Harih om or Harih om tat sat. The word "Hari" is widely used in later Sanskrit and Prakrit literature, Hindu, Buddhist, Jain and Sikh religions. It appears as 650th name of Vishnu in the Vishnu sahasranama of the Mahabharata and hence rose to special importance in Hindu Vaishnavism.
