The seer Ganapati Muni associated the Mahavidyas with "prakasha" ("Light") and "nada" ("Sound") in stages of creation. Chhinnamasta is the violent interaction between the Light and the Sound enabling Creation. Chhinnamasta severing her own head is interpreted symbolic of the disconnecting of the Source and the manifest Creation, similar to cutting the umbilical cord between the mother and the new-born. Further, Chhinnamasta is associated with thunder and lightning, interacting light and sound forces. Her epithet, Vajra Vairochani ("radiant like the vajra"), is linked to the "vajra" (thunderbolt) and its divine master - Indra, the king of heaven and the god of rain, thunder and lightning.
