What are the two fundamental paths of life discussed in Chapter 17 of the Sai Satcharitra, and how are they different?

Chapter 17 of the Sai Satcharitra elaborates on two distinct paths: Shreya, the path of the Good or Salvation, and Preya, the path of the Pleasant or Worldly Joy. The text describes them as being opposite in nature, like light and darkness. Shreya is the form of discrimination and pure knowledge (Vidya), leading to one's true self-interest. In contrast, Preya is the form of ignorance (Avidya), driven by cravings for sensory objects, wealth, and status. According to the chapter, while the wise and courageous cling to Shreya, those who are dull-witted are conquered by Preya and fall away from their ultimate purpose.
