When you understand that seeing is happening and then you look, defilements don’t arise. When you know that seeing is happening and then look, the mind pays attention to the concept but defilements don’t have a chance to come because understanding is present.
After you know that you’re seeing, you look; after you know that you’re hearing, you listen. After you know that there is an object and the mind, then you pay attention to the concept. It’s not a big problem.
Without concepts, we also cannot do anything, right?
