("in the direction of the right") Circumambulation is the act of walking around an item or person as a demonstration of regard or respect.
The walker's right side (considered the purer and more
fortunate side) is always oriented toward the item or per son being circled.
A person's parents or instructor, a deity's image, a temple,
a city, or the whole Indian subcontinent may all be ringed in this way.
The pradakshina is the term for one of the architectural
elements seen in many bigger temples, particularly those built in the Nagara
architectural style.
In this example, it's a semicircular processional passageway
that circles the temple's primary image, allowing worshippers to circumambulate
it before or after devotion.
Pradakshina is also the fifteenth of the sixteen traditional
upacharas ("offerings") made to a god as part of devotion, based on
the idea of treating the deity as a distinguished guest.
The fundamental aim here, as with all the upacharas, is to
demonstrate one's devotion for the god and to minister to the deity's needs in
the same way as one would attend to the needs of a real person.
