What does Chapter 17 teach about the concept of 'Purushartha' and its connection to overcoming worldly suffering?

In Chapter 17, 'Purushartha,' or true human effort, is presented as a pivotal concept. The text explains that the unfathomable wheel of worldly existence, 'Samsara,' causes man to suffer unendurable torments. When a person becomes exhausted by this sorrow, they begin to search for a way to stop this painful cycle. It is at this moment, by great fortune, that 'true manhood (Purushartha) is born.' This effort is directed toward choosing the path of Shreya (the Good) over Preya (the Pleasant). The chapter defines the true purpose of human life as discarding Preya and honoring Shreya, urging individuals to strengthen their intellect and struggle for Shreya's sake to resist obstacles and achieve true self-interest.
