This is the most important, fundamental and profound sentence in Buddhism.
Explain with "fate": there is here, there is no here; If you gather, you will live, but if you disperse, you will die.
Literal explanation: everything is born by coincidence, and the change of things has no master.
Long-winded explanation: The characteristic of this world is that in the process of constant movement and change, you and I get to know each other: a question and answer, a question and answer is a kind of karma, which starts with a question and answer and ends with a question and answer. It is reflected in the movement and change, and there is no master.
All the above sentences about fate have the same meaning.
Karma in Buddhism is quite different from what you said.
Only by deepening Buddhism can we have a deeper understanding of cause and effect.
Good luck with everything.
