An elderly Falun Dafa practitioner posted Dafa banners in a suburban area. At first, he hesitated to post a banner on the front side of an electricity pole. When he tried to post the banner on the backside of the pole, he fell into a hole in the ground. He thought, "I am doing such a good deed, why did I fall into such a dirty place?" With this one righteous thought, he came out of the hole instantly. Then he posted the banner on the front side of the pole. Master said, "We have said that good or evil comes from a person's spontaneous thought, and the thought at that moment can bring about different consequences" (Zhuan Falun).
One day, I posted a truth-clarifying flyer in the Military-Police Coordination Office building. As soon as I posted the flyer, a big policeman approached me and asked, "What are you doing?" Several more police and personnel appeared at this moment. I answered calmly, "I am here to do a good deed." His attitude changed instantly upon listening to my words. He responded nicely, "Next time, post the flyers elsewhere." I enlightened to a principle that when we do Dafa work, we must be firm and righteous in our thoughts and actions so that we will leave no loopholes for the evil to take advantage of.
On another occasion, a fellow practitioner and I posted truth-clarifying flyers in a dorm yard. We were spotted by a vicious security guard. He ordered us to remove the flyers. My fellow practitioner said slowly, "Our Teacher sent me here to save you all, no one should remove the flyers." Then we walked out calmly. When we looked back at that evil man, he was standing there without moving. Our righteous thoughts had "frozen" him and prevented him from doing any further damage to Dafa.
On another day, I went shopping on my bike. I spotted a slogan that slandered Falun Dafa written in white chalk on an electricity pole. I knew that there were three people hiding around and they were responsible for that slogan. I thought to myself that I was a particle of Dafa and I could rectify all that is not righteous. So I slowly erased the evil slogan with my gloves. One of the people emerged from the hiding place and walked towards me. I was not scared at all. I told him "freeze!" Then I walked away calmly. Just like Teacher described, "If you are not afraid, the factor that would make you afraid will become non-existent. This is not to be self-imposed, but is achieved by calmly and truly letting go of it" ("Eliminate Your Last Attachment(s)").
