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

Chapter 17 of the Sai Satcharitra presents a fundamental distinction between Shreya and Preya, describing them as being as opposite as light and darkness. Shreya is defined as the path of salvation and the Good, representing pure knowledge (Vidya) and wisdom. In contrast, Preya is the path of worldly joy and the Pleasant, which is rooted in ignorance (Avidya) and a lack of discrimination. The text explains that an individual whose mind is drawn to Preya ultimately deviates from their true self-interest, whereas the wise and fortunate choose to cling to Shreya. This core teaching from Chapter 17 emphasizes that choosing Shreya over Preya is the true purpose of human existence.
