Memory and imagination are tools, and the tools are either useful or destructive on the way we use them. Often the emotion around these tools is fear. We fear our past repeating itself, or we fear our worst imagination coming true. Most times, we brush our fears under the carpet. But the real way to calm your fears is to confront them and claim them.
We imagine the worst, reject the best, neglect possibilities, and avoid our responsibilities. Fears reside in our shadow-self. But we do not have to fight the shadow, we just have to be the Light.
