In the Tibetan language, kha means sky, celestial space, or emptiness; dro is a sentient female being who is dancing or otherwise in motion. The Tibetan kha'dro (in Sanskrit, dakini) is variously translated as "celestial woman," "space goer," or "sky dancer."

These
goddesses are embodiments of wisdom and compassion who appear in the
meditations, dreams, and visions of human beings to help them in their
quest for enlightenment. They represent the sacred union of body and
mind in meditation, a place where wisdom and emptiness meet and become
one, and come to assist us in overcoming physical and spiritual
obstacles to awakening.
