Why do we do pradakshina (circumambulate)?

We cannot draw a circle without a center point. The Lord is the center, source and essence
of our lives. Recognizing Him as the focal point in our lives, we go about doing our daily
chores. This is the significance of pradakshina.
Also every point on the circumference of a circle is equidistant from the center. This means
that wherever or whoever we may be, we are equally close to the Lord. His grace flows
towards us without partiality.
