According to Chapter 17, why do people find it so difficult to choose the path of Shreya over Preya?

As detailed in Chapter 17, even when a person understands the difference between Shreya (the Good) and Preya (the Pleasant), making the right choice is difficult. The text suggests that a 'dull-witted person is conquered by Preya and embraces it.' This struggle arises because as long as one has an obsession with worldly desires like 'gold and women,' and the senses crave external objects, Preya remains irresistibly sweet. People get caught in the cycle of maintaining their body, family, wealth, and status, which makes them pursue Preya. This is why the chapter states that though both paths are within reach, a person without discrimination is incapable of making the right distinction.
