Boudhanath is a UNESCO World Heritage Site situated in northeastern Kathmandu. The stupa in Boudhanath is the largest in Nepal and the holiest Tibetan Buddhist temple outside of Tibet.
The Boudhanath stupa is rich in Buddhist symbolism. From above, it looks like a giant mandala. with four of the Dhyani Buddhas mark the cardinal points, and the fifth, Vairocana, enshrined in the centre. The five Buddhas also personify the five elements (earth, water, fire, air and ether), which are represented in the stupa's architecture.
Kora is a transliteration of the Tibetan word which means circumambulation. It is an action performed by the practitioner circling around a sacred site or object as part of a ritual.
