What is the unavoidable role of a saint, and what happens when one receives their grace, as explained in Chapter 30?

According to Chapter 30, the task of uplifting their own devotees is 'always unavoidable for saints.' Sai Baba is even called the 'Acharya (teacher) of the assembly of saints,' for whom this duty is inescapable. The chapter explains the profound impact of a saint's grace, stating that whomever they bestow it upon 'attains inconceivable great power.' This grace also brings the 'wealth of discrimination between Self and non-Self,' meaning all knowledge is attained. Holding the feet of a saint like Sai is said to cause the dissolution of all sins and make the spiritual path fearless.
