Who The Gandharvas and Apsarases is
In the oldest hymns there is hardly a tribe of Gandharvas at all. There is the Gandharva, one bright being high up in the air. The word comes about twenty times in the Rigveda, and only three of those speak of more than one.
He is hard to see clearly, and the poets seem to like him that way. He stands upright on the vault of the sky. He has bright weapons and wears a sweet-smelling robe. He measures out the middle air. He guards the place of Soma, the drink of the gods, and watches over the families of the gods. One hymn calls him Vishvavasu and asks him to help the singers tell true from false. In two hymns Indra is his enemy, which scholars connect with his jealous watch over Soma.
Beside him is the Apsaras, a woman of the waters. She smiles at her lover in the highest heaven. One hymn names the Gandharva in the waters and the water woman as the parents of the twins Yama and Yami. Another says that the long-haired wandering sage walks the path of the Apsarases and Gandharvas. Only one Apsaras has a name in the Rigveda. She is Urvashi, who lived four autumns with a human king and left him.
The Gandharva also comes to every wedding. A bride, the wedding hymn says, belongs first to Soma, then to the Gandharva, then to Agni, and only then to her husband. So Vishvavasu is honoured, and asked to get up and leave.
The Atharvaveda knows them as a crowd. It counts thousands of Gandharvas. They and their wives live in the big fig trees and banyans, where their lutes and cymbals can be heard. The Apsarases love dice and can give luck in play. Both can also trouble the mind, and there are charms to drive them off.
Scholars have guessed that the Gandharva was once the rainbow, or the moon, or a spirit of wind or cloud. The hymns do not settle it. Macdonell concluded only that he was a bright being of the sky, sometimes thought of as living in the waters with his wife.
Upright he has climbed the sky, the Gandharva, his bright weapons turned toward us. He wears a fragrant robe, lovely to look at.
