If you don’t, you are putting yourself in a prison and that prison is inside of your head. Evil is nothing more than fear. Fear gives power over to evil. Then, bad things happen in your life over and over and over again until you finally say, “you know what… I give in. I give up my attempt at control.”
It seems quite evident to me that people do NOT believe that science and spirituality can co-exist. If they didn’t, however, then neither would we. Everything begs to be challenged in some way. That is the nature of duality and it is the way of our world. Without spirituality, there would be no philosophers to ask the bigger questions. Without science, there would be no physicians to give answers.
