Listen ever so deeply with your whole being. Anything less is a waste of time. But don't listen to me. Listen to what's inside you. You and I are constantly constructing a sense of the world. It's quite possible that what is called "one's world" is not that same as reality. So look deeply. Perhaps, you (and I) can get a glimpse of what's real beyond "my world" or even "our world". That would be true science, true wisdom.
