How does the author describe Sai's essential nature and his own role in writing the Satcharitra in Chapter 50?

Chapter 50 portrays Sai Baba as the 'Unmanifest' who has taken form, an embodiment of pure consciousness. Despite this divine stature, He is described as desireless yet deeply compassionate towards faithful and loving listeners. The author, Hemad, expresses his own humility, questioning his power as a 'wretched one' to describe Sai's glory. He concludes that he is merely an instrument, stating that it is Sai Himself who, 'out of love for his devotees, reveals this book through grace.' This passage underscores the belief that the Satcharitra is not a human creation but a divine revelation.
