You wrote that only seeing nobody who sees and no visual objects. You have answered that is a deep state of mind, and should I throw it away. That is not enlightenment. I should continue to practice bravely. How can I do that? How do I throw it away?

As long as there is still awareness remaining that you are only seeing, only hearing, you need to also throw that awareness away and only become the seeing and hearing, not even aware of seeing and hearing anymore as something separate from yourself. From there you can have the intuitive experience of oneness, which brings forth great amazement and joy.
