I believe a sense of suffering changes based on evolving levels of self-awareness. People experience different intensities of suffering. As a person evolves to understand the reson behind each perception, this becomes a means to move beyond or transcend different kinds of suffering that no longer bother you to the same degree. You can grow to believe certain experiences are good for your growth because they prompt you to stretch your mind and deepen your self-understanding. Some people also evolve to believe suffering is an illusion. You may decide this if you are on that energy frequency.
