(Minghui.org) When my child was in middle school, he attended a physics after-school class on the weekends. There were over a dozen students in his class, and parents could stay in the back of the classroom to wait.

During the second lesson, the teacher, a woman in her 40s, suddenly changed the subject and asked the students a question: “Have you heard of Li Hongzhi?” I was at the back of the room and was shocked to hear that, sensing that she might defame Falun Dafa. The students, all around 14 years old, responded that they had never heard of this person (the founder of Falun Dafa). She then began to slander Dafa with lies from the Chinese Communist Party propaganda.

I immediately sent out a powerful, righteous thought, with a giant word “eliminate” covering the space field. The teacher instantly became very still, as if “frozen” in place, standing with mouth and eyes wide open, one arm raised in the air with a finger pointing to the back of the room. She tried to talk but could not say a word, just “hmmm” sounds. She maintained that rigid posture for several minutes until I stopped sending righteous thoughts.

The students were puzzled by the teacher’s behavior, and she felt embarrassed too. She must have passed on a lot of false and negative information to many students over the years, and I decided to help her to learn the truth about Falun Dafa. So I tried to seek her out after the class, but she hastily disappeared.

After the next class, I waited at the door of the classroom to try to meet with the teacher. I walked up to her when she came out and greeted her with a smile. I said, “Teacher, about the topic of Falun Dafa, you mentioned in the last class, I’d like to talk to you about it.”

I told her that Falun Dafa is not a cult and it’s not on the State Department’s list of cults. I opened the webpage on my phone and showed her. She stared at the page with surprise and scrolled through it to the end. After not seeing Falun Dafa on the list, she lifted her head, “I understand now! I understand!” and left.

I believe that this teacher now realizes the truth and that in the future she will no longer defame Dafa.
