Second is the door of forgetting. Some wounds are too deep to heal, or too deep to heal quickly. As it so happens, many memories are simply too excruciating, and there is no healing to be done. The saying "time heals all wounds" is false. Time heals most wounds. The rest are hidden behind this door. Third is the way of madness. There are times when the mind is dealt such a blow it hides itself in insanity. There are times when reality is nothing but pain, and to escape that pain the mind must leave reality behind. Last is the door of death. The final resort. Nothing can hurt us after we are dead, or so we have been told.
