Deep Listening is listening to everything all the time, and reminding yourself when you're not. But going below the surface too, it's an active process. It's not passive. I mean hearing is passive in that soundwaves hinge upon the eardrum. You can do both. You can focus and be receptive to your surroundings. If you're tuned out, then you're not in contact with your surroundings. You have to process what you hear. Hearing and listening are not the same thing.
