) — is often interpreted as an expression of an ancient perception that the Chinese polity (or group of polities) occupied the center of the world, with other lands lying in various directions relative to it. A second interpretation suggests that ancient symbols such as the axis mundi lie in a particular philosophical or metaphysical representation of a common and culturally shared philosophical concept, which is that of a natural reflection of the macrocosm (or existence at grand scale) in the microcosm (which consists of either an individual, community, or local environment that shares the same principles and structures as the macrocosm). In this metaphysical representation of the universe, mankind is placed into an existence that serves as a microcosm of the universe or the entire cosmic existence, and who — in order to achieve higher states of existence or liberation into the macrocosm — must gain necessary insights into universal principles that can be represented by his life or environment in the microcosm. In many religious and philosophical traditions around the world, mankind is seen as a sort of bridge between either: two worlds, the earthly and the heavenly (as in Hindu, and Taoist philosophical and theological systems); or three worlds, namely the earthly, heavenly, and the "sub-earthly" or "infra-earthly" (e.g., the underworld, as in the Ancient Greek, Incan, Mayan, and Ancient Egyptian religious systems). Spanning these philosophical systems is the belief that man traverses a sort of axis, or path, which can lead from man's current central position in the intermediate realms into heavenly or sub-earthly realms. Thus, in this view, symbolic representations of a vertical axis represent a path of "ascent" or "descent" into other spiritual or material realms, and often capture a philosophy that considers human life to be a quest in which one develops insights or perfections in order to move beyond this current microcosmic realm and to engage with the grand macrocosmic order. In other interpretations, an axis mundi is more broadly defined as a place of connection between heavenly and the earthly realms — often a mountain or other elevated site. Tall mountains are often regarded as sacred and some have shrines erected at the summit or base. Mount Kunlun fills a similar role in China. Mount Kailash is holy to Hinduism and several religions in Tibet. The Pitjantjatjara people in central Australia consider Uluru to be central to both their world and
