Why does Guanyin want to be a lotus platform?

Because avalokitesvara is a bodhisattva, and the bodhisattva is sitting on the lotus platform. In Journey to the West, when the Monkey King was true and false, the Monkey King killed the fake Wukong (Liu Er's macaque). Because of his distrust of Tang Priest, Wukong was heartbroken and wanted to go back to Huaguoshan. The Tathagata said to him, "Don't be paranoid. I taught Guanyin to see you off, but I'm not afraid he won't accept it. Just keep him safe, and then you'll be in bliss, and you'll also take the lotus platform. " It can be seen that monkeys are at least the same level as Guanyin after learning the scriptures. So not all immortals can sit on the lotus platform, so they got a certain level, and Guanyin can naturally sit on the lotus platform at this level.
