Chapter 30 contrasts learned Brahmins with simple devotees. What is the underlying message about the nature of devotion and grace?

The underlying message in Chapter 30 is that divine grace transcends scholarly knowledge and ritualistic expertise. The chapter mentions learned Brahmins from pilgrimage sites performing recitations and reading sacred texts, then contrasts them with simple devotees who feel they are of 'little power' and 'devoid of proper samskaras'. The crucial insight provided in Chapter 30 is the declaration: 'Even if everyone abandons us, Sai does not forsake us.' This powerfully suggests that sincere faith and complete trust are more valuable than intellectual prowess. Sai's grace is bestowed upon whomever He chooses, granting even the simplest devotee 'inconceivable great power' and the ultimate knowledge.
