Analyze the role and inescapable duty of a saint as portrayed in Chapter 30 of the Sai Satcharitra.

Chapter 30 presents a profound analysis of a saint's fundamental purpose, using Sai Baba as the ultimate example. The text explicitly states, "The task of uplifting one's own devotees is always unavoidable for saints." This duty is not a choice but an intrinsic and inescapable aspect of their being. Sai Baba is even lauded as the 'Acharya' or teacher of all saints, for whom this responsibility is paramount. This uplifting is not merely material but deeply spiritual. The chapter describes how a saint's grace can bestow "inconceivable great power" and the "wealth of discrimination between Self and non-Self," which is the essence of all knowledge. This portrayal elevates the role of the Guru from a simple guide to a compassionate, powerful force essential for a devotee's liberation and spiritual progress.
