I believe that "god" is a collective energy. Humanity. In the musical Les Miserables it says: "To love another person is to see the face of god." I believe this is true in a figurative sense. When we love others, we are most plugged into Humanity. We feel happiness. We are most receptive to feeling the collective energy of those around us.
I believe that we as humans have no pre-set purpose for existing. "Why are we here?" is a moot, generalized question. Why does that deer exist up there on that mountain? Why did that serf exist in 1344? Irrelevent, all of it. We are part of the circle of life, just the same as billions of humans before us, just the same as all living things. And so, because I have no specific guideline or reason for existing (other than simply "I exist"), I set for myself a purpose. And that purpose is to experience all walks of life and culture. My self-determined reason for existence is to find and cherish the Best of Humanity. (subtopic for another time: how to define the "Best of Humanity")
I believe that I am responsible for my own actions. I can choose to do something, or not choose it, and my reasons are my own. The way I interpret others' actions is based on my own life experiences and insecurites, and is therefore biased. The way others interpret my actions is based on their own life experiences and insecurities, and is therefore biased. No one can truly and exactly understand another human being. But I find I'm most at peace with myself and am positively connected to the collective energy of Humanity when I'm actively engaged in trying to understand others. I believe that relationships are most functional when the parties involved care enough to put themselves into their partner's place and look at things from their point of view. It's a journey, a path, but one without destination. Just walking the path of Trying To Understand is courageous and speaks volumes as to one's priorities.
I believe that attacking others based on your own personal preferences or opinions of how life ought to be is destructive and counterproductive. I believe to do so actually pulls one further from Humanity, and creates a harder time of plugging back in.
