Which female deity with three faces and a vase is associated with long life?

The female deity with three faces and a vase associated with long life is Ushnishavijaya.

Ushnishavijaya, also called Namgyalma in Tibetan Buddhism, is a prominent Mahayana and Vajrayana goddess. Her name means “Victorious One of the Ushnisha,” referring to the Buddha’s cranial protuberance, a symbol of spiritual attainment and protective power. She is linked with longevity, purification of karma, protection, and relief from suffering.

In Tibetan tradition, she forms one of the Three Deities of Long Life alongside Amitayus and White Tara. Her standard iconography includes three faces—usually white, yellow, and blue—and eight arms holding ritual objects. The vase is an important longevity symbol, connecting her with the preservation and purification of life.

A common mix-up is Amitayus, who is also strongly associated with long life but is a male Buddha depicted holding a vessel of immortality. White Tara is another longevity deity, generally recognized by her seven eyes. Ushnishavijaya is also associated with a widely recited dharani, believed in Buddhist tradition to lengthen life and purify harmful karma.
