Continually asking questions about the reasons for the existence of the evil can only weaken us; and wanting to suppress it is a company doomed to fail. In winter, against the rain, the snow, the storm, the cold, what do we do?
Are we leaving home to order the forces of nature to calm down? In tales, yes, there are things like that, but in everyday life, we take care of our house, we consolidate it, we check the insulation, we install proper heating, and that's it, we are quiet.
Well, that's how wisdom tells us to act with evil. Instead of struggling directly with him, one must only become more resilient to better understand and perform better. Thus, the darkness that is in other circumstances should overwhelm us, on the contrary, helps to strengthen, ennoble and improve our health.
