Based on Chapter 30, what is described as the most fundamental and unavoidable duty of a saint like Sai Baba?

Chapter 30 defines a core, non-negotiable responsibility for all saints, including Sai Baba. The text states with certainty, "The task of uplifting one's own devotees is always unavoidable for saints." This principle is presented as a fundamental aspect of a Guru's existence. The chapter further elevates Sai Baba's role by calling him the "Acharya (teacher) of the assembly of saints," and then reinforces the point by stating that even for Him, this sacred duty of uplifting followers is "inescapable." This highlights that a saint's primary, binding purpose, as described in this chapter, is to guide, support, and ensure the spiritual elevation of their devotees.
