Buddha Sakyamuni said that people have eight kinds of suffering.
They are birth, old age, illness, death,
Resentment and hatred meet, love is separated, the five Yins are blazing, and what you seek cannot be obtained.
People in the world think that the greatest pain is not getting what they want.
Now I know it's not.
When I taste the ninth kind of bitterness,
Can't stay apart,
It's not what I want, I can't leave it,
Heaven and earth, there will be no end to death.
