Tara (Sanskrit: तारा, tārā; Tib. སྒྲོལ་མ, Dölma) or Ārya Tārā, also known as Jetsun Dölma (Tibetan language:rje btsun sgrol ma) in Tibetan Buddhism, is a female Bodhisattva in Mahayana Buddhism who appears as a female Buddha in Vajrayana Buddhism.
She is known as the “mother of liberation”, and represents the virtues of success in work and achievements. She is known as Tara Bosatsu (多羅菩薩) in Japan, and occasionally as Duōluó Púsà (多羅菩薩) in Chinese Buddhism.
Tara is a tantric meditation deity whose practice is used by practitioners of the Tibetan branch of Vajrayana Buddhism to develop certain inner qualities and understand outer, inner and secret teachings about compassion and emptiness. Tara is actually the generic name for a set of Buddhas or bodhisattvas of similar aspect.
These may more properly be understood as different aspects of the same quality, as bodhisattvas are often considered metaphors for Buddhist virtues.
