(Minghui.org) My father is in his 70s, and he has been cultivating Dafa for more than 10 years. He has been persistent and steady in his practice and also of telling people about Falun Dafa.

However, one day he came home exhausted, suffering thereafter with a severe headache for many days. He continued to study the Fa and do the Dafa exercises the best he could. Our whole family practices Falun Dafa, so we all encouraged him to look within and figure out the reason for his tribulation. We also sent forth righteous thoughts with him, yet he did not improve.

About a week later, while we were doing the meditation, my father was once again suffering with a headache. He asked Master to give him a hint as to why he was suffering.

After meditation, I decided to lay down and take a rest. As I was drifting off to sleep, I had a vision: I saw two piles of seafood on my father's bed. One pile consisted of shellfish and the other was a pile of various other fish. It was apparent that the fish died from lack of water, as some were still struggling to survive. I then awoke.

I went to my father immediately to see how he was doing, and I told him about my vision. My father told me that when he was young, he often caught various shellfish and other fish. Then he admitted that even after he started practicing Falun Dafa, he bought live fish several times and had the merchant kill them for him. Later, he realized that it was not a good thing for a practitioner to do, so he stopped doing it.

We seemed to have found the root cause of his problem, and his headaches disappeared. It was a great lesson for the entire family. I decided to share this cultivation experience with other practitioners who may have encountered similar situations.

We must be serious on the issue of not killing. I overheard a practitioner mention that he had let go of the mentality of not killing because he thought he had reached a high enough level. He said he also observed another practitioner buying live scallops.

As such, I would like to remind practitioners to be serious about the issue of killing.
