According to Chapter 17, why do people choose the path of Preya even when it's not in their ultimate self-interest?

Chapter 17 clarifies that people, particularly those described as dull-witted, choose the path of Preya due to ignorance and obsession with worldly objects. The text notes that as long as one has an obsession with gold and women, and the senses crave worldly things, Preya will seem sweet. Even when a person understands both paths, the choice is difficult. As Chapter 17 states, a dull-witted person, caught in the cycle of maintaining their body, cattle, children, and wealth, is easily conquered by Preya and embraces it, forsaking their true purpose.
