Can you explain the concept of surrendering one's 'me-ness' as prayed for by the devotee in Chapter 26?

The concept of surrendering one's 'me-ness' in Chapter 26 is a plea for the complete dissolution of the ego and individual identity into the Guru. The devotee asks Sai Baba, 'let You Yourself become my "me-ness"'. This entails relinquishing all sense of personal agency and experience. The text elaborates on this by showing the devotee asking to have their body-consciousness taken away, to be moved like a puppet according to the Guru's will, and to be freed from worrying about pleasure and pain by having the Guru take on those experiences Himself. As described in Chapter 26, this is the pinnacle of surrender, where the devotee seeks to remove the 'I' that separates them from the divine, hoping to achieve a state of natural union, or 'Sayujya,' through the Guru's grace.
