How does this text suggest I can overcome the ego and the feeling of 'I and mine'?

To overcome the ego and the delusion of 'I and mine,' Chapter 17 offers specific advice. It instructs you to recognize that the confusion of bodily ego is like a mirage and that you should actively become free of this sense of 'mine-ness'. You are advised to tell yourself that you are the pure Brahman, temporarily deluded by Maya and the company of the body. The text suggests you must 'wake up yourself and quickly come back to your true form.' As long as the sense of 'me and you' persists, you cannot see your own welfare. Therefore, you should discard it, look at your own Self, and follow the Sadguru's word with faith, always keeping your focus on the Self.
