"If there is a destiny, we will never separate; if there is no destiny, we will not come together; if we gather together, we will disperse without destiny. Don't cherish the fate and think hard." It is not from Buddhism and it is not a poem~ This is a purely literary poem.
Literally explained:
Destined to never break up: That is to say, if there is really a fate, it is destined by fate and they will not break up.
Gathering without destiny: People who have no destiny will not come together.
Getting together and then breaking up without destiny: Since we got together but broke up again, it is also a situation of no destiny.
Cherish fate and don’t think too hard: Cherish fate and don’t think too much. It means that it is destiny, and it means to follow the fate.
