Representation of chakrawahn, i.e. the cosmos. In both Hindu and Buddhist cosmology, it describes the planes and realms in which all beings can be reborn and consists of a vertical cosmology and a horizontal cosmology. The former is divided into three realms, known as the Triloka, while the latter, also known as sahasra, describes the grouping of these vertical worlds. Mt. Meru, the mythological and sacred mountain, is believed to be the centre of this universe.
