Consciousness

When one contemplates their own consciousness, the concept of self quickly
arises. Everything you think is self contained. You and only you are thinking about your own consciousness. It is very easy to believe the universe revolves around you. With this in mind, the selfish and unthoughtful actions of so many people makes more sense. They don't even realize they are this way because they are the center of the universe.

Be aware that you are not the center of the universe and that your actions have a much larger impact.
