Buddhism separates two things we usually confuse: what happens, and what we add to what happens.
The first is pain. The second — the resistance, the rehearsal, the story about how it should not be like this — is where most suffering lives.
The ancient teaching
“Struck by an arrow, an untrained person is struck by a second arrow: their own reaction to the first.”
ParaphraseParaphrase of the Sallatha Sutta (Samyutta Nikāya 36.6)
A well-known compression of the sutta's teaching, not a literal translation of the Pali.
What does this mean today?
This is the most immediately testable teaching in the library. The next time something goes wrong, watch for the second arrow — the twenty minutes of arguing with reality.
Buddhism does not promise no first arrows. It offers a real reduction in the number of arrows you fire at yourself.
