Can you explain the author's plea for complete surrender to Sai Baba as mentioned in Chapter 26?

In Chapter 26, the author expresses a deep yearning for total surrender to Sai Baba. He asks Baba to take away his body-consciousness and ego, stating, "from now on, You look after Your own—there is no 'me-ness' left in me." The author goes further, requesting to be moved like a puppet according to Baba's will and for his restless mind to be restrained. In a powerful expression of devotion, he even asks Sai Baba to become his "me-ness," to experience the pleasure and pain on his behalf, thereby freeing him from all worldly worries and fixing his love entirely on the Sadguru.
