An Apsara (also spelled as Apsarasa) is a female spirit of the clouds and waters in Hindu and Buddhist mythology.
An Apsara (Sanskrit: अप्सराः apsarāḥ, plural अप्सरसः apsarasaḥ, stem apsaras-, a feminine consonant stem, អប្សរា), is also known as Vidhya Dhari or Tep Apsar (ទេពអប្សរ) in Khmer, Accharā (Pāli) or A Bố Sa La Tư (Vietnamese), Bidadari (Indonesian & Malay), Biraddali (Tausug), Hapsari or Widodari (Javanese) and Apson (Thai: อัปสร). English translations of the word "Apsara" include "nymph," "celestial nymph," and "celestial maiden."
Apsaras are beautiful, supernatural female beings. They are youthful and elegant, and superb in the art of dancing. They are often the wives of the Gandharvas, the court musicians of Indra. They dance to the music made by the Gandharvas, usually in the palaces of the gods, entertain and sometimes seduce gods and men. As caretakers of fallen heroes, they may be compared to the valkyries of Norse mythology. As ethereal beings who inhabit the skies, and are often depicted taking flight, or at service of a god, they may be compared to angels.
