I am Japanese...I know, no one believes me...but people always send me stuff about the green and white tara's in tibetin budhisim. (not to mention all the other colors she is) but I then discovered the following about a Japanese version...(off some website...is this copywriting?) (oops) My painting is based on what I beleive she is. Not a direct interpretation, but who I am when I invoke her, believe in her, wish I was her...I'm not really sure...But the painting is me as her? I guess...

Not until the 4th century AD and the teachings of Asanga, who introduces the Yogachara system -- which stressed meditation as the path toward enlightenment -- does the feminine principle gain acceptance in Mahayana traditions. Around the 6th century, the goddess Tara was considered the Sakti of Kannon/Avalokitesvara (sometimes depicted as his wife). In the 7th century, the Chinese pilgrim Xuanzang claimed to have seen many statues of this deity in northern India. However, she was not accepted by followers of the Theravada, and her image is rarely found in Sri Lanka or in Southeast Asia (except in Java, where a temple was dedicated to her in 779). Many legends have sprung up around this goddess. According to one, she was born in a beam of blue light emanating from one of the eyes of Avalokitesvara (see Kannon above). In Tibet, around the 7th century, came the idea that virtuous and pious woman were incarnations of Tara. Two of the wives of King Srong-btsan Sgam-po of Tibet -- the Chinese woman Wencheng and the daughter of Nepal's Amsuvarman -- are considered to be manifestations of Tara. To differentiate between the two wives, the Tibetans created two distinctive Taras, white for the Chinese, with a full-blown lotus as her emblem, and green for the Nepalese, whose emblem is the blue (half-open) lotus. Each was supposedly born from an eye of Avalokitesvara (open and half-closed). Hence they came to be considered as symbols of the day (full-blown lotus, eye open) and the night (half-open lotus, eye half-closed). In China, this goddess is not well known or represented. In Japan, she was given the rank of Bodhisattva (Tarani Bosatsu), where her manifestation combines both colors, but she is found only rarely in Japan, and usually only on mandalas or on temple banners. She holds a pomegranate (symbol of prosperity) and a lotus, and is normally depicted in pale green color (in Japan, the word for blue can also be used for the color green)
