Can you explain the concept of complete surrender as described in the prayer within Chapter 26?

The prayer in Chapter 26 details a profound state of total surrender to the Sadguru. It involves laying one's ego at the Guru's feet and completely relinquishing the sense of 'me-ness'. The devotee asks Sai Baba to take away their body-consciousness, stating they no longer need the knowledge of pleasure or pain. This surrender is so complete that the devotee asks to be moved according to the Guru's will, like a puppet. An alternative plea is made for the Guru to become the devotee's very 'me-ness' and take on the experience of pleasure and pain Himself, freeing the devotee from all worry. This signifies a desire to dissolve the individual will entirely into the divine will of the Guru, as mentioned in the chapter.
