What is the powerful willpower that drives a person to maintain their morality and conscience? Is it something learned, or are we born with it? Is the cost of sustainable goodness constant control, or is it the ability to remain on the path? When I created this work, I didn't have a simple idea of hell in mind. I had the idea of a human being's own internal hell. In fact, this idea is something we often consider in tests of willpower at the limits of morality and conscience. Perhaps hell is also within us in heaven, and when we take wood to hell, a fire grows, while when we take wood to heaven, it becomes a sapling.
