There are hundreds of yantra designs related to deities, principles, and planet
The Shri Yantra, called the “queen of yantras,” (rajayantra) is the symbol of the great divine mother principle, the source of all energy, power, and creativity. Vedic traditions, specifically the Shri Vidya school of tantra, regard the design as the representation of the universe as well as the body of the the goddess related to the feminine principle of shakti, or energy. Every line, triangle, and lotus petal symbolizes a specific type of shakti.'
