A very long time ago, Avalokitesvara, Guanyin in Chinese, vowed that if she ever became disheartened in saving sentient beings, may her body shatter into a thousand pieces. Once, after liberating countless beings from the hell realms by teaching them the Dharma, she looked back down into the hell realms. To her horror, she saw that the hell realms were quickly filling up again!
In a fleeting moment of despair, she felt profound grief. And in that moment, in accordance with her vow, her body shattered into a thousand pieces. She beseeched the Buddhas to help and many did. Like a fall of snowflakes they came. One of those Buddhas was Amitabha. He and the other Buddhas helped to re-form her body into one that had a thousand arms and hands, with an eye of wisdom in each hand. In this way, she could better help all sentient beings.
Guanyin Bodhisattva is also known as "She Who Hears the Cries of the World."
Right now, our world is crying for help. She is listening.
