The Ten Swords Are the Only Criterion for Testing Truth

My master always told us to cut down trees to catch fish, water flowers and plant fields, But I travel around the mountains and rivers, listen to music on the fence, and call it the truth of cultivation. One day, I asked my master for advice: "Master, what are the exercises of our sect? The master replied: "Dialectics... Oh no, practice Dafa." "Then why are you called the Master of Truth?" "Because they envy the teacher's practical ability!" I have always wondered what practice is. Until that day, the master's wife was kidnapped by her enemies. I saw the master smiling and taking me away in the air. Then the world spun and the demons and monsters turned into ashes. Only then did I understand that what the master said was "The Ten Swords are the only criterion for testing truth!"
