Hari (Sanskrit: हरि) is among the primary epithets of the Hindu preserver deity Vishnu, meaning 'the one who takes away' (sins).
The Sanskrit word "हरि" (Hari) is derived from the Proto-Indo-European root "*ǵʰel- to shine; to flourish; green; yellow" which also gave rise to the Persian terms zar 'gold', Greek khloros 'green', Slavic zelen 'green' and zolto 'gold', as well as the English words yellow and gold.
The same root occurs in other Sanskrit words like haridrā, 'turmeric', named for its yellow color.
In Hinduism, beginning with Adi Sankara's commentary on the Vishnu sahasranama, hari became etymologized as derived from the verbal root hṛ "to grab, seize, steal", in the context of Vaishnavism interpreted as "to take away or remove evil or sin",[2] and the name of Vishnu rendered as "he who destroys samsara", which is the entanglement in the cycle of birth and death, along with ignorance, its cause;[3] compare hara as a name of Shiva, translated as "seizer" or "destroyer".
(SGGS, Ang.1313)[5]In the Varan Bhai Gurdas, an early explanation and interpretation of Sikh theology, Bhai Gurdas also associates the name "ਹਰਿ" (Hari) in the form of Hari Krishan in the Dwapur Yuga with the letter "ਹ" (h) in "ਵਾਹਿਗੁਰੂ" (Waheguru).
