Tara  (སྒྲོལ་མ, Dölma), also known as Jetsun Dölma appears as a female  bodhisattva in Mahayana Buddhism, and 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. Tārā is a meditation deity  revered by practitioners of the Tibetan branch of Vajrayana Buddhism to  develop certain inner qualities and to understand outer, inner and  secret teachings such as karuṇā (compassion), mettā (loving-kindness),  and shunyata (emptiness).
