What are the main teachings about the nature of a true saint, like Sai Baba, as detailed in Chapter 12?

Chapter 12 teaches that a true saint embodies qualities of supreme compassion and detachment. It describes Sai as the 'king of knowledge personified' who is inseparable from the Supreme Soul. A key teaching is the saint's equal vision; the text states that for Sai, 'the pauper and the king are the same.' He possesses great power yet remains renounced, and has extreme affection for all beings while being detached from worldly things. This chapter posits that saints are the 'sun for the darkness of ignorance' and will expend their own merit, drawn by the love of their devotees, to help them overcome obstacles and achieve spiritual progress.
