Deva

Deva (Devanagari: देव) is the Sanskrit word for deity (female devī). Derived from the root div, "to shine or become bright," a deva is a “shining one.”

H. P. Blavatsky defined it as follows:

Deva (Sk.). A god, a “resplendent” deity. Deva-Deus, from the root div “to shine”. A Deva is a celestial being—whether good, bad, or indifferent. Devas inhabit “the three worlds”, which are the three planes above us. There are 33 groups or 330 millions of them.
