Quan Yin Pu Sa saving all sentient being is a small, animated screensaver, designed to bring some peace to your desktop.
Avalokitesvara means one who looks from the beyond at the world, who is keeping himself in body-form, in mind-form - he is keeping the whole ladder. He has gone beyond, but he is keeping the whole ladder to help, out of compassion. The last desire, to help people - that too is a desire - keeps him in existence.
