Describe the scene where Sai Baba gives permission to write his life story. What were his conditions and promises?

As detailed in Chapter 2, Sai Baba, feeling compassion for the author's impatient mind, granted permission to create a collection of his stories and experiences. He told the author to keep a record and promised his full help. However, Sai Baba clarified that the author was merely a "pretext" and that He Himself would write the story. The main condition was for the author to completely dissolve his ego and surrender it at Sai's feet. In return, Sai promised not only full assistance with the story but also His service in all aspects of the devotee's life, stating He would enter with "I-ness" and write with His own hand.
