Selfishness is such a powerful spiritual force that the thought of getting rid of it hardly ever crosses our mind. In order to know ourselves we need to look at ourselves from outside, to feel something different other than ourselves, to compare ourselves to something outside of us.
Surrounding objects are perceived because they are made up of the same selfishness. Otherwise they would remain invisible. Selfishness takes many forms. Its most restricted form is the one that can only perceive itself. This is the perception that man has in our world. We are so selfish that we can only perceive ourselves.
