What is the primary distinction between the paths of Shreya and Preya as detailed in Chapter 17 of the Sai Satcharitra?

Chapter 17 of the Sai Satcharitra explains that Shreya (the Good) and Preya (the Pleasant) are as different as light and darkness. Shreya is the path of salvation, representing pure Knowledge (Vidya) and wisdom, which aligns with one's true self-interest. In contrast, Preya is the path of worldly joy, representing pure Ignorance (Avidya) and a lack of discrimination. The chapter states that he whose mind runs toward Preya falls away from his true purpose. While the wise are never deluded by Preya, the ignorant do not find Shreya appealing.
