A while ago, I took a free online course in Scientology. Its purpose was to explain how we interrelate and how everything is striving to survive throughout all our relations. So also this crow, who came for a munchie.
I think people simply add their own games or believe they are fighting to survive, even when they have their needs met. I found the Scientology Dynamics to be a parallel to Maslow's Hierarchy of needs. What drives you to do what you do, and is any lack in one area impacting any other in your life?
