The Green Tara is an activity goddess who is full of youthful vigor and power. She is called Syamatara in Sanskrit and Sgrol-Ijang in Tibetan. She is a very fierce form of Tara but yet still very compassionate. Many consider her as the original form of Tara.
The Avalokiteshvara even consider her as their consort. For the Buddha Amitabha, She is an emanation of the "self born." They also depict that the Tara`s head is an image of the Amitabha. She is believed to be to have come into existence as a result of the incarnation of the wife of Srong-brtsan-sgam-po who was a king of Tibetan. The color green is symbolic in Buddhism signifying activity full of accomplishment. Therefore the Lord of action, Amoghasiddhi is also associated with her because of the color green.
In her iconography, her posture is depicted in such a way that it signifies her readiness and ease to take an action. Her right leg is left outstretched while her left leg is folded in a position that is contemplative. Her right hand is placed in a posture granting boon while her left hand is placed in a gesture or mudra of granting refuge according to the belief. In her closed hands, she holds blue utpalas (lotuses) to signify power and purity and she is considered to be adorned with Bodhisattva jewels of richness.
