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

Chapter 17 of the Sai Satcharitra explains that Shreya and Preya are two fundamentally opposite paths. Shreya is described as the path of salvation or 'the Good,' which is rooted in pure knowledge (Vidya) and wisdom. Conversely, Preya is the path of worldly joy or 'the Pleasant,' which stems from ignorance (Avidya) and a lack of discrimination. The chapter emphasizes that those who are drawn to Preya fall away from their true self-interest, while the wise are not deluded by it. Shreya is the choice of the intelligent and fortunate, leading to ultimate well-being.
