According to the beginning of Chapter 30, what is the primary and unavoidable duty of a saint like Sai Baba?

The opening verses of Chapter 30 clearly define the fundamental responsibility of a saint. The text explicitly states, 'The task of uplifting one's own devotees is always unavoidable for saints.' This is presented not as a choice, but as an inherent and inescapable duty. The chapter elevates Sai Baba by naming him the 'Acharya (teacher) of the assembly of saints,' emphasizing that even for the leader among them, this sacred obligation to guide and elevate followers is paramount. This establishes that a saint's purpose, as described in Chapter 30, is intrinsically tied to the welfare of their devotees.
