Emotions are not a reliable guide to the way the world works. But they can teach you where to look for things you are clinging to. Anger is like a compass pointing straight toward the things you most fear.
Once, the Buddha said, “Monks, I often think on two things: safety and solitude. I am pleased by kindness avoiding harm to others. I often think, ‘By doing this I will hurt nobody, either the weak or strong.’ I am pleased by solitude. I often think, ‘Unskillful things have been left behind.’ You too should be pleased by safety and solitude. You too should think these thoughts.”
Most of your life is an illusion. We are such compulsive thinkings that we literally spend most of our lives thinking about our lives rather than living them. It is hard to simply have an experience without seeing it through the veil of opinions and views. This isn’t only our memory of things but the experiences we have in real time.
There is no such thing as pure objectivity. All experience is a mix of the subjective and objective. This isn’t a problem to be solved, it is simply part of the human condition. Nobody else can truly share your experience. You help to create your reality through what you read, practice, and do. Subject doesn’t mean fake. There is nothing more real than your subjective experience, after all. In a real sense, it is the world.
