Trivikram त्रिविक्रम

Means "he who has made 3 strides" in the Rigveda.He is called by epithets such as vi-chakra-manas . The Sanskrit word chakra also means "wheel". That may have suggested the idea of Vishnu carrying a chakra.

Vishnu can travel in three strides. The first stride is the Earth. The second stride is the visible sky. The third stride cannot be seen by men and is the heaven where the gods and the righteous dead live. This feature of three strides also appears in the story of his avatar Vamana called Trivikrama.
