Based on the teachings in Chapter 23, what is the role of a saint, and how should one perceive them?

Chapter 23 of the Sai Satcharitra explains that the primary role of a saint or Guru is to guide souls out of the delusion of Maya and onto the path of loving devotion (Bhakti Yoga). Saints are described as incarnations who appear on earth out of benevolence for the 'salvation of dull-witted souls.' The chapter strongly advises against judging them by external appearances, such as their caste or what they eat, noting that their true state is beyond such things. This is illustrated by the story of the Yogi who judged Baba for eating onions. Ultimately, a true Guru like Sai is one who 'colors His devotees in His own hue' and can show the soul, which is like a parrot trapped in a cage, the path to true freedom.
