Human figure The human body can express the symbol of the world axis. Some of the more abstract Tree of Life representations, such as the sefirot in Kabbalism and the chakra system recognized by Hinduism and Buddhism, merge with the concept of the human body as a pillar between heaven and earth. Disciplines such as yoga and tai chi begin from the premise of the human body as axis mundi. The Buddha represents a world center in human form.

Astrology in all its forms assumes a connection between human health and affairs and celestial-body orientation. World religions regard the body itself as a temple and prayer as a column uniting earth and heaven. The ancient Colossus of Rhodes combined the role of the human figure with those of portal and skyscraper. The Renaissance image known as the Vitruvian Man represented a symbolic and mathematical exploration of the human form as world axis. Homes Secular structures can also function as axis mundi. In Navajo culture, the hogan acts as a symbolic cosmic center. In some Asian cultures, houses were traditionally laid out in the form of a square oriented toward the four compass directions. A traditional home was oriented toward the sky through feng shui, a system of geomancy, just as a palace would be.

In many archaic dwellings the central pillar does in fact serve as a means of communication with the heavens, with the sky."
