I read about a prayer of complete surrender in Chapter 26. What exactly is the author asking of Sai Baba?

The prayer in Chapter 26 is a profound expression of total surrender and the dissolution of ego. The author asks Sai Baba to take complete control, pleading, "Move me according to Your will like a puppet, and restrain my mind." He goes so far as to lay his ego at Baba's feet, declaring, "from now on, You look after Your own—there is no 'me-ness' left in me." As detailed in this chapter, the author asks Baba to remove his body-consciousness and even experience pleasure and pain on his behalf, so he no longer has to worry about them. This highlights a deep yearning to completely merge the individual self into the Guru's will.
