Devi is the Sanskrit root-expression of Divine; its related masculine term is Deva. Devi is synonymous with Shakti, the female part of the divine, as conceptualized by the Shakta convention of Hinduism. She is the female partner without whom the male aspect stays weak and void. Goddess love is a necessary part of Hinduism.
