Chapter 17 uses several analogies to describe the concepts of Shreya and Preya. Can you explain the analogy of the swan and the milk?

In Chapter 17, the path of Shreya (the good) and Preya (the pleasant) are said to be blended together, just as milk can be mixed with water. The text then presents the analogy of a swan, or Maral, which is believed to have the unique ability to separate milk from water and drink only the pure milk. In the same way, this chapter teaches that courageous, intelligent, and wise individuals are like the swan. They can discriminate between the two paths and will cling only to Shreya, the path of salvation, while turning away from the worldly temptations of Preya. This analogy highlights the importance of wisdom in making the right life choices.
