According to Chapter 17, why do some people pursue worldly pleasures, and what does it take to choose the spiritual path instead?

Chapter 17 explains that individuals who lack discrimination and detachment find the path of Preya (the pleasant) to be sweet. These 'dull-witted' people, caught in the cycle of maintaining their body, cattle, children, wealth, and status, embrace Preya. To choose the path of Shreya (the good) requires courage, intelligence, and wisdom. As described in Chapter 17, the wise are able to turn away from Preya and cling only to Shreya, like a swan that drinks only pure milk from a mixture of milk and water, which is the true purpose of human life.
