Could you describe the concept of complete surrender as expressed in the prayers within Chapter 26?

The concept of surrender in Chapter 26 is one of total and absolute submission of the self to the Guru. The author makes a profound plea to Sai Baba, laying their ego at His feet and declaring that no "me-ness" remains. This surrender involves asking Baba to take away body-consciousness and the need for pleasure or pain, requesting to be moved according to the Guru's will like a puppet. The prayer goes even further, asking Baba to become the devotee's very "me-ness" and to take on the experiences of life, so the devotee may find unwavering peace at the Guru's feet. This illustrates a deep yearning for the dissolution of the individual ego into the will of the divine Guru.
