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

As detailed in Chapter 17, people struggle to choose Shreya because Preya appears sweet to those who lack discrimination and detachment. The text explains that as long as there is an obsession with gold and women, and the senses crave worldly objects, Preya will remain appealing. Even when a person understands both paths and the choice is within their control, making the right decision is difficult. The chapter states that a dull-witted person, caught in the cycle of maintaining their body, family, and wealth, is often conquered by Preya and embraces it instead of Shreya, the path of true self-interest.
