Talking about Sarasvati, she is one of the oldest of the Indian goddesses. Aerial photography has shown the outlines of ancient channels of the river Sarasvati in India that support the claim of a river culture that was the origin of the civilization. This contradicts the notion that invaders from the Caucasus populated India and brought civilization.

Her Tibetan name dbyangs can ma points to her status as consort of Manjushri. She's the "art woman" who brings out his talent as Manjughosha--gentle music. Hindus and Buddhists alike revere her as a teacher of all the arts that make a person an educated member of society.         

Another thing about Sarasvati, the goddess of eloquence and learning. Her name means "having (vati) an abundance of streams, pools, lakes (saras)." As the goddess of the great river, she appears already in the Rig Veda.
