Green Tara

"She is known as the Mother of Mercy and Compassion. She is the source, the female aspect of the universe, which gives birth to warmth, compassion and relief from bad karma as experienced by ordinary beings in cyclic existence.
She engenders, nourishes, smiles at the vitality of creation, and has sympathy for all beings as a mother does for her children. As Green Tārā she offers succor and protection from all the unfortunate circumstances one can encounter within the samsaric world."
