The Shri Yantra, also known as the 'Sri Chakra' is one of the most powerful of all Vedic talismans. The grid of this talisman consists of nine concentric triangles, of which four point upwards and five point downwards. All these triangles have sides of equal length and the nine major triangles intersect to form 45 more, smaller triangles. This configuration represents a balance between the divine masculine and feminine powers, Shiva and Shakti, as they exist in the Universe. This grid forms a multi-stage concentration of positive spiritual energy. This energy is focused on a central point in the talisman grid, which is representative of the centre of the Universe.
Among other things, this talisman also forms the abode of the Goddess of wealth, 'Mahalakshmi' and brings luck, success and wealth and other manners of good fortune.
