What does Buddhism often say that "all beings are predestined" mean?

Buddhist scriptures say: Ten Buddhas in the Third World share the same dharma body. Ten directions refer to space, and the third direction refers to time (past, present and future). The ten buddhas are all sentient beings; * * * The same body is the same body.

"All sentient beings are predestined friends", that is to say, all sentient beings are related. What does it matter? It means "the same body", that is, the same body
