Bhagavad Gita 2.63
"From anger comes delusion; from delusion, confusion of memory; from confusion of memory, ruin of intelligence; and from ruin of intelligence one perishes."
Modern interpretation
In the middle of the day, return to this: Anger is expensive: it costs you clarity, then memory, then choice. Pay attention before it bills you.
Practical action
Before responding to the thing irritating you, draft your reply, wait ten minutes, then re-read it.
Reflection question
What boundary is this anger asking me to set, calmly?
