How does the author of the Shri Sai Satcharitra describe his own qualifications and the inspiration behind writing the book in Chapter 25?

In Chapter 25, the author humbly states that he felt he lacked the necessary authority, knowledge, or erudition for the task of writing Shri Sai's life story. He refers to himself as a "poor soul" and an "ignorant person." However, he explains that the project was not his own initiative but a divine mandate. He states that Sai Baba Himself inspired the desire in his heart and gave him the direct command to "Keep the records." As described in Chapter 25, this divine instruction endowed his meager intellect with courage and special knowledge, making him realize that he was simply an instrument for Sai to awaken His own devotees.
