What does the word Hari mean? How does it denote the Supreme Being ?

The word Hari does have many meanings. The specialty and uniqueness of the Vedas is that the very same Vedas that speaks about those occult ideals that are out of reach of the human intellect, like, life after death, heaven, hell etc., also proclaims that Hari is the Supreme Being. This very fact is the ‘Pramana’ (authority) for holding Sri Hari as the Supreme Being.
