(Minghui.org) I will never forget the day September 25, 2008. I was on a flight to New York to attend a martial arts competition, and I learned about Falun Dafa. Since then, I have practiced Falun Dafa, which is based on the principles of Truthfulness-Compassion-Forbearance. The practice has cleansed my mind and body.

One day in 2013, I developed a stomachache, and I vomited whatever I ate. At first I did not take it seriously and thought it would soon end. However, it worsened, and I steadily lost weight. I felt extremely tired, but my mind was clear. I enlightened that it was a test.

I looked within based on the Fa for any reason that could have caused this problem. I realized there were two possible causes, one was because of my karma from the past, and the other was interference from the old forces. I thought that whatever the reason was, I would pass the test if I did the three things well. I knew that if one is on a divine path, the path is intricate and has challenges. I continued to study the Fa, do the exercises, and save sentient beings. I made up my mind that nothing could sway me from Falun Dafa and helping Master to save people.

Although I was steadfast, my health continued to deteriorate. Within 30 days, my weight decreased from 150 lbs to 120 lbs. I could not stand up to do the exercises; I could only do the fifth exercise, the sitting meditation. I felt excruciating pain at night. I tossed and turned in bed, while clenching my hands.

I struggled as if I had reached the end of my life. My wife saw this. Although she is also a practitioner, she could not help asking me to see a doctor. I replied, “That is not a place I should go.”

A true practitioner does not have diseases. I know that hospitals and medicine are for ordinary society and do not work for genuine practitioners. However good the medicine is, it is made of materials of molecules in this dimension, which would not solve the root problem. What we have cultivated is high energy matter from other dimensions. How can we compare man-made medicine to high energy matter?

When I think of Master' Fa, I have confidence, and I eliminate interference with righteous thoughts. I am sure that I have a lot of high energy matter, and I believe that I can overcome all those tests.

My mind was very firm and determined, regardless of the pain. By the beginning of September, although I had been trying to negate the sickness karma with righteous thoughts, I had not completely eliminated it. Several times, I had felt extreme pain while at work, and was concerned that others would see my suffering and develop negative thoughts about Dafa.

Thus, I went into my office and closed the door. When I could not tolerate the pain, I lay on the floor and clenched my teeth and fists and rolled back and forth on the floor. I asked Master for help. I sometimes recited Master's Lunyu, and sometimes I did the sitting meditation.

Master said, “I am rooted in the universe. If anyone could harm you, he or she would be able to harm me. Put simply, that person would be able to harm this universe.” (Zhuan Falun)

Then I asked myself, “Am I a Dafa disciple?” I said to myself firmly, “Yes. Even though I did not do the three things well. I am a Dafa disciple. Nobody can change my mind about Dafa or about helping Master to rectify the Fa and saving sentient beings.”

Subsequently, with righteous thoughts, I passed test after test. During this period, our local practitioners went out with petitions that called for the end of forced organ harvesting from imprisoned practitioners in China. Even though I was in such critical physical condition, I insisted on going out with the other practitioners to collect signatures. While out, although I did not feel a lot of pain, I could not eat. Even when I ate just a little bit, I threw up. I could not walk much, had to stop to rest, and then continued to collect signatures.

With the symptoms I had, most people would not be able to go out and collect signatures. But I could. Why? Because I am a Dafa disciple, not an ordinary person. It is our mission to collect signatures. Saving sentient beings cannot be delayed. My righteous thoughts motivated me to finish the task with the other practitioners.

About 50 days later, with righteous thoughts, I passed the test and could eat again. One day there were some red spots on my legs, and they were very itchy. I just laughed at it. These tiny itchy spots were nothing compared to my previous tests. They disappeared one week later. My body gradually recovered, and within a year I returned to my previous weight.

Looking back at those 50 days in which I had the sickness karma, each day seemed very long, like a year. I was always thinking, “What if I have to go to the hospital?” I would have incurred a huge cost, both in my cultivation and financially. However, I am different from an ordinary person, and I recovered because of my belief in Dafa. Through the test, I felt the power of Dafa, which is supernatural, powerful, and miraculous.

I wrote to remind other practitioners that if we encounter any physical tribulation, we need to believe in Master with our strongest righteous thoughts, and eliminate all negative thoughts. Once we have negative thoughts, we are aligned with the mindset of the old forces. The results will be negative. Only when we maintain our righteous thoughts can we have a positive outcome and overcome the tribulation.

When you believe in Dafa, you will notice how many practitioners survive such critical tests. Do not dwell on those few who have passed away. These two numbers are not proportional.

When some practitioners had a sickness test, at first they treated it in an ordinary way. At the superficial level, they understand Master's Fa. However, when they encounter sickness karma, they respond as ordinary people. If you do not position yourself as a genuine practitioner, how can a miracle occur for you?

As a genuine practitioner, if you whole-heartedly believe in Dafa, without any doubt, you can overcome any interference.
