I once saw Guanyin Bodhisattva throw herself into a beautiful woman. I wonder if it is predestined relationship with Guanyin Bodhisattva? Is there a moral? Please know,

This is absolutely wrong. There is no such thing as possession in Buddhism.

Possession, is definitely a foreign demon, how can it be a bodhisattva.

Everyone should be conscious of Buddhism, eat their own food, go their own way and achieve Buddhism by themselves. How can you treat possession as a dirty thing?

Bad practice? Therefore, what you see is by no means avalokitesvara. You must break this illusion and stop this abnormal relationship.

If you are predestined friends with Guanyin Bodhisattva, you should learn from the compassion and behavior of the Bodhisattva and learn more about the basic teachings of Buddhism, instead of being misled by superstition or even evil thoughts.
