Based on the introduction of Chapter 24, what are the defining characteristics of Saints, and how does Sai Baba fit this description?

Chapter 24 begins by defining the nature of Saints, the righteous, and Great Souls. It describes them as being 'always pure, stainless, and without blemish.' To illustrate this point, the text uses the metaphor of a 'sky that is clear and cloudless,' emphasizing their pure and faultless character. Immediately following this description, the chapter discusses the worship of Maharaja Sai, implying that he embodies these very qualities. It is mentioned that worshiping him helps one attain both worldly success and the supreme goal (Parmartha), which aligns with the role of a Great Soul guiding devotees.
