In Vajrayāna Buddhism, Tārā is worshipped as the female Buddha of Enlightened Activity. There are twenty-one different emanations of Tārā in the Tibetan pantheon. The foremost (Ārya Tārā) among them is Syamatara; i.e., Green Tārā, commonly known as Jetsun Dölma in Tibet. Indeed, Dölma is one of the most popular meditational deities or yidam (Sanskrit: iṣṭadevatā) amongst tantric practitioners in the Tibetan tradition. In fact, the deity is believed to be an embodiment of all the Buddhas' enlightened wisdom, wherefore she came to be seen as the "Mother of all Buddhas".
Green Tārā is also considered a tantric savioress, for indeed, the meaning of the Sanskrit word tāra is 'protector' or 'liberator'. She offers protection from nature disasters, wild and poisonous animals and insects, evil people, and malevolent spirits. Furthermore, by the grace of her divine mercy and compassion, Green Tārā eliminates any of the Dharmic obstacles which her devotees may encounter along their spiritual path.
