This is the Sri Yantra, one of the oldest and most powerful symbols. It's the Hindu symbol for Creativity and Enlightenment. It is conceived as a place of spiritual pilgrimage. It represents the cosmos at the macrocosmic level and the human body at the microcosmic level 〰each of the circuits correspond to a chakra of the body.
A rare combination of ancient Hindu and Buddhist symbols: the solar disc, related to the deity Vishnu, the trident of Shiva, representing the unity of past, present and future, and the eightfold lotus, alluding to Enlightenment and the Path.
