Pain comes to every human. It is a vital aspect of life in the physical world. How one person reacts to pain may differ from another. This you call a “threshold,” reflecting one’s tolerance for pain. Some can take very little, and others seemingly quite a lot. Why the difference? For life is about the experiences, and what each person—each soul—learns from these experiences. If all had the same pain threshold, there would not be so much learning, but it is not necessary to suffer in order to learn.
You can learn simply by taking control of your thoughts, and in this way raise your threshold to such a degree that what previously may have pained you no longer affects you at all. A miracle, you say? Not at all. Simply the learning of another lesson. Pain is not necessary. Tolerance goes up and down for a reason. May you suffer little, having learned well that pain begins with perception.
