What does Chapter 17 of the Sai Satcharitra identify as the true purpose of human life and the effort required to achieve it?

The true purpose of human life (Purushartha), as stated in Chapter 17, is to consciously discard the path of the Pleasant (Preya) and honor the path of the Good (Shreya). This choice is likened to a swan that separates milk from water. The text emphasizes that this requires significant human effort. One must first strengthen the intellect to firmly understand where Shreya lies. Then, as obstacles inevitably arise on this path, one must struggle and resist them fully. Chapter 17 encourages this struggle for the sake of Shreya, stating that this is where true human effort stands firm, enabling one to achieve their ultimate self-interest.
