The Buddha's Instruction on Knowing the Eye, Invisible Objects, Ear and Sound, Nose, Nast, and Smell

In our usual mode of experience, experiencing the world, we habitually reference all experience back to a sense of self. So what is the Buddha saying here that's special or different from our ordinary way of understanding or living? This is an important and critical difference. It's not difficult to see the play of different objects as they arise in the course of a day and the course of all lives. What's difficult is to see them as being conditioned as being selfless, not I, not mine.
