Yogi: At home I’m impatient, but at the retreat I become patient; I worry that I’ll be impatient again when I go home. What shall I do?

Sayadaw: If you keep practicing at home, you’ll continue to be patient, but if you stop, you’ll return to being impatient again. You change because of the practice.

Impatience is anger – impatience arises because the dosa defilement is strong. If at home, awareness and samadhi become weaker, then impatience will return.

That is why meditation should not stop.
