In the sanctum, Trivikraman is standing in a huge size with his left leg raised aloft to indicate that his one step has measured the sky.

The image has only two hands, the right exhibiting Tarjani mudra and the left extended as far as the stretched leg. Vishnu has ordinarily three poses. Sitting (Asana), Recumbent (Sayana) and Standing (Sthanaka). In Kanchi itself one can see all the poses sitting in Pandavaperumal coil, sayana in Yatodkari and standing here.
