A thousand hands will naturally come to your aid as long as you are kind and there is love in your heart. You will reach out with a thousand hands to help others.
Guan Yin is the bodhisattva of compassion, revered by Buddhists as the Goddess of Mercy. Her name is short for Guan Shi Yin.
Guan means to observe, watch, or monitor;
Shi means the world;
Yin means sounds, specifically sounds of those who suffer.
Thus, Guan Yin is a compassionate being who watches for, and responds to, the people in the world who cry out for help.
