Due to our habits, we are often partial, fixating on dualities, such as subject and object, good and bad, I versus you (or them), my world versus the outside world, right and wrong, and so on. This partiality leads us to label things endlessly. But if we look closely, we discover that much of it is unnecessary and not at all useful. These fixations that impede an open and pure view can be both subtle and coarse.
