Green Tara is traditionally seen as playful virgin and White Tara as wise, mature and voluptuous woman. There are several fierce/wrathful manifestations of Tara as guardian/protector and as destroyer. In the West, we tend to equate these energies with "crone" though that is a naive and culturally ageist tendency. The Tara of Tibetan Buddhism embodies the motherly energy of protection; She is concerned not with creating life, but with sustaining and protecting it.
