The so-called Martial Arts Heart was not about being exceptionally loyal, virtuous, or righteous. Martial Arts had nothing to do with good or evil; in truth, the Martial Arts Heart was simply a Martial Artist's resolve in their pursuit of the martial path.
To practice Martial Arts was to contend with the heavens for one's destiny. The path was filled with various hardships, dangers, and temptations. If one's will was not firm, it would be easy to lose their Martial Arts Heart, abandon their training, and watch all their previous efforts go to waste.
