Srividya sadhana involves worship of Sri Yantra by Srividya mantra
The Shri Vidya is a Tantric tradition of Shaktas. It maintains a monistic metaphysics, that ultimately there is only one reality in the cosmos, the reality of consciousness identified with the Goddess Tripurasundari. Tripurasundari, a tantric form of Shri/Lakshmi, is manifested in her mantra (called the shri vidya mantra) and in her sacred diagram of nine intersecting triangles within a circle (the shri Yantra or Sri cakra). The Shri Vidya devotee seeks for liberation from the cycle of reincarnation (samsara) by realising his identity with the Goddess.
