Devi is a Sanskrit word meaning the female aspect of divinity. It is related by definition to the English word Goddess. Devi is also used in the International Nath Order as a suffix to the name or cryptonym given at initiation and indicates an initiated female Nath.

Devi is the Divine Mother, the goddess of strength, who has an equal role with the male aspect of divinity. She is energy or Shakti, without which the male aspect, which represents consciousness, is powerless. It is said that “Shiva is shava (a corpse) without Shakti.”
