Unique among all forms of sacred architecture, the stupa is the quintessential symbol of enlightenment, the primordial sacred structure for all Buddhist traditions. While the stupa has historically appeared in different shapes, all of its forms connect the inner realm of experience with the outer physical cosmos… Stupas are empowered with relics of Buddhas, the Great Guru Padmasambhava, Arhats and other holy beings.
