What is the relationship between ego, divine assistance, and the authorship of Sai Baba's stories as described in the source material?

The source material from Chapter 2 establishes a direct and inverse relationship between the author's ego and the flow of divine assistance. Sai Baba explicitly states that the author is 'merely a pretext' and that He, Baba, will write His own story. The primary condition for this is that the author 'should dissolve his ego and surrender it at my feet.' When the ego is dissolved and no trace remains, Baba promises, 'I myself shall enter with I-ness and write with my own hand.' This illustrates that complete surrender and the annihilation of personal ego are the prerequisites for becoming a pure channel for divine work.
