Describe the specific promise Sai Baba made about his role in writing the biography, and the condition attached to it.

As detailed in Chapter 2, Sai Baba made a very specific and profound promise regarding the creation of his biography. He promised the author, "I myself shall write my own story!" and stated that the author was "merely a pretext." This divine intervention, however, came with a critical condition: the author must completely dissolve his ego and surrender it at Baba's feet. If this condition was met, Baba assured him of full assistance. He explained that once the ego is gone, "I myself shall enter with 'I-ness' and write with my own hand." This illustrates that the work was to be a divine act channeled through a surrendered devotee.
