What was Sai Baba's specific instruction to the author about writing His stories, and what role did Baba say He would play in the process?

According to Chapter 2, when the author sought permission to compile a collection of stories, Sai Baba granted it with a profound condition. Baba stated, "He is merely a pretext; I myself shall write my own story!" He instructed the author to dissolve his ego and surrender it at His feet. In return for this complete surrender, Sai Baba promised His full assistance, not just for the book but in all aspects of the author's life. He explained that when the ego is gone, He himself enters with 'I-ness' and writes with His own hand, making the author a mere instrument for the work.
