Can you explain the difference between Shreya and Preya as described in Chapter 17 of the Sai Satcharitra?

Chapter 17 of the Sai Satcharitra presents a detailed contrast between the paths of Shreya and Preya, describing them as being as opposite as light and darkness. Shreya is defined as the path of the Good or Salvation, which is the form of discrimination and pure Knowledge (Vidya). Conversely, Preya is the path of the Pleasant or worldly joy, characterized by a lack of discrimination and ignorance (Avidya). The chapter explains that an individual whose mind is drawn towards Preya will ultimately fall away from their true self-interest, whereas the wise are never deluded by it. This fundamental distinction sets the stage for the spiritual choices a person must make.
