What does Chapter 17 say about the true purpose of human life, or 'Purushartha', and the effort required to achieve it?

In Chapter 17 of the Sai Satcharitra, the true purpose of human life, referred to as 'Purushartha', is defined as the conscious act of discarding Preya (the pleasant path of worldly joy) and honoring Shreya (the good path of salvation). This is not an easy task and requires significant human effort. The chapter explains that this journey often begins when a person becomes exhausted by the sorrows of worldly existence and starts searching for a way to end the suffering. This inquiry marks the birth of true 'Purushartha'. The text encourages one to strengthen their intellect and struggle for the sake of Shreya, firmly resisting the many obstacles that will arise on the path.
