The eye will continue, even after inlit it shuts down. It's the function of the mind. If every part of the body continues to function then you don't think you're the ego any more. Nera hankara, but it's very difficult to do it directly. How do you do it? Ner mamaha, psychology. Here, you have to thin out the ego before you can step back from it. The way to do it is first attack the mind, before you attack the eye.
Inspired by the 15th chapter of the Ashtavakra Gita, Swami Sarvapriyananda gives a discourse on the nature of the Self.
