How does Sai Baba describe the relationship between a devotee's ego and His own divine intervention in the writing of the sacred text?

Sai Baba establishes a clear and profound relationship between the devotee's ego and His divine action, as described in Chapter 2. He instructs the author, who is to be a mere pretext, to completely dissolve his ego and surrender it at Baba's feet. Only when the ego is dissolved and no trace of it remains can Baba's divine intervention fully manifest. At that point, Sai Baba states, 'I myself shall enter with 'I-ness' and write with my own hand.' This illustrates that surrendering the personal ego is the prerequisite for divine will to operate through the devotee. Baba promises full assistance and service to one who achieves this state, ensuring that the work is accomplished by the One to whom it truly belongs.
