How does Chapter 17 use an analogy to describe how a wise person chooses between the path of salvation and the path of worldly pleasure?

Chapter 17 employs a powerful analogy involving a swan (Maral) to explain how a wise person navigates the choice between Shreya (salvation) and Preya (worldly pleasure). The text states that just as milk and water can be mixed, so are these two paths blended in life. However, courageous, intelligent, and wise individuals are like the mythical swan that can drink only the pure milk from the mixture at Manasarovar lake. As this analogy from Chapter 17 illustrates, such fortunate souls cling only to Shreya and consistently turn away from Preya, demonstrating their power of discrimination to separate the truly good from the merely pleasant.
