9 Circles of Sri Yantra

The different parts or petals and lines of the yantra are usually arranged in concentric circles (mandalas) and contain rays or sub-limbs of devi. The Shri Yantra has nine of these mandals, each filled with various aspects of the Devi. In Shri Yantra there are 111 aspects. The Shri Yantra is said to be a geometric form of the human body, which implies that goddess as Macrocosm is one with human being as Microcosm. See 9 Malndalas.
