Imagine a small pond in a quiet garden. When the water is still, you can look down and see everything clearly — the stones, the fish, the sky reflected like a mirror. This is the mind that is calm (平靜的心,像平靜的池塘).
Now imagine a child throws a stone into the pond. Splash! The water jumps, ripples spread everywhere, and the surface becomes messy. Suddenly you cannot see clearly at all. A strong feeling — anger, stress, or being overwhelmed — is just like that stone. It makes the mind react, and everything becomes cloudy.
But here is the secret: you do not have to throw another stone back. You can stop. You can inhale slowly, and exhale slowly. You can focus on your heartbeat and wait. Little by little the ripples fade, and the water becomes still again. This waiting — not reacting — is called nonreaction (不反應). With the steady power of Right Effort (Vīrya), you choose calm, and you see clearly once more.
