According to Chapter 30, what is the inherent duty of a saint, and how does Sai Baba fulfill this?

Chapter 30 states that the task of uplifting one's own devotees is an unavoidable responsibility for saints. Sai Baba, who is called the 'Acharya (teacher) of the assembly of saints,' perfectly exemplifies this role. The chapter describes how those who hold onto His feet achieve the dissolution of all sins and find their path becoming 'fearless and obstacle-free.' Furthermore, it is mentioned that Sai Nath completely knows the heart's desires of His devotees and is singularly capable of fulfilling them, leading to their fulfillment. By bestowing grace, He grants 'inconceivable great power' and the 'wealth of discrimination between Self and non-Self,' thus fulfilling the saint's ultimate duty of spiritual upliftment as described in Chapter 30.
