The Tibetan mandala is a tool for gaining wisdom and compassion and generally is depicted as a tightly balanced, geometric composition wherein deities reside. The principal deity is housed in the center. The mandala serves as a tool for guiding individuals along the path to enlightenment. Monks meditate upon the mandala, imagining it as a three-dimensional palace. The deities who reside in the palace embody philosophical views and serve as role models. The mandala's purpose is to help transform ordinary minds into enlightened ones.
