Devi, Mother of the World, Prakriti, Lalita Tripurasundari, the Red Goddess.

"Dear One, Tripura is the ultimate, primordial Shakti, the light of manifestation. She, the pile of letters of the alphabet, gave birth to the three worlds. At dissolution, She is the abode of all tattvas, still remaining Herself" From Vamakeshvaratantra
