What are the two primary paths of life discussed in Chapter 17 of the Sai Satcharitra, and how do they differ?

Chapter 17 of the Sai Satcharitra elaborates on two distinct life paths: Shreya and Preya. Shreya is described as the Good, representing the Path of Salvation, pure Knowledge (Vidya), and wisdom. In stark contrast, Preya is the Pleasant, representing the Path of Worldly Joy, ignorance (Avidya), and a lack of discrimination. The text emphasizes that these paths are as opposite as light and darkness. He whose mind pursues Preya falls away from his true self-interest, whereas the wise are never deluded by it. According to Chapter 17, choosing Shreya over Preya is the very purpose of human life.
