We are all one. There's no denying it. Quantum physicists will tell you about the field - God, Source, The Universe - that responds to, not only everything we do but from everything we think. You've all had that experience of thinking about someone and then they call. Spiritual teachers will tell you that we are spiritual beings living a physical experience and that we are all connected at the level of source - much like the waves upon the ocean - we are all the ocean. Everything you do or think not only effects you but also effects your world. For some fascinating research read Lynne McTaggart's The Field or the Intention Experiment.
