Since Avalokitesvara is compassionate, he responds to the cries of all beings with the desire to help them (hence his name).
Guanyin seems to be a Chinese translation of Sanskrit Avalokitesvara.
As in Pure Land Buddhism, the case of Avalokitesvara exemplifies attitudes about human destiny.
That is to say, in Pure Land, going to Sukhavati was the overriding human destiny of choice.
