Why hindus walk clockwise in temple around the God?

The Lord is the center, source and essence of our lives. Hindus acknowledge this by performing Pradakshina. Recognizing Him as the focal point in our lives, we go about doing our daily chores. This is the significance of Pradakshina.

According to Adi Sankaracharya, real Pradakshina is the meditation that thousands of universes are revolving around the Great Lord, the unmoving center of all forms.
