The principal belief of Vishnuism is the identification of Vishnu as supreme or principal worship of him as was the case in the Historical Vedic times. Hopkins writes: there is a passage like the great Ka hymn of the Rig Veda, 'whom as god shall one worship?' The sages say to Vishnu: All men worship thee; In the Rig Veda he is referred by his name of trivikrama (who took three strides) and is believed by some scholars as the starting point of the evidence of such worship.
