What does Chapter 30 reveal about the fundamental duty of a saint towards their followers?

According to Chapter 30, the primary and unavoidable task for saints is the uplifting of their own devotees. The text emphasizes that this responsibility is so fundamental that even for Sai Baba, who is described as the 'Acharya (teacher) of the assembly of saints,' this duty is inescapable. This highlights the deep, inherent commitment a true spiritual master has towards the spiritual and worldly welfare of those who have placed their faith in them, a core theme presented in this chapter of the Sai Satcharita.
