The largest stupa in Nepal, Bodnath is the center of Tibetan Buddhist faith and culture in Kathmandu and rich in Buddhist symbolism. From above, Bodnath Stupa looks like a giant mandala, or diagram of the Buddhist cosmos. And as in all Tibetan mandalas, four of the Dhyani Buddhas mark the cardinal points, with the fifth, Vairocana, enshrined in the center (in the white hemisphere of the stupa). The five Buddhas also personify the five elements (earth, water, fire, air and ether), which are represented in the stupa's architecture. There are other symbolic numbers here as well: the nine levels of Boudhanath Stupa represent the mythical Mt. Meru, center of the cosmos; and the 13 rings from the base to the pinnacle symbolize the path to enlightenment, or "Bodhi" - hence the stupa's name.
