According to Chapter 17, what is the ultimate purpose of human life, and what is required to fulfill it?

The ultimate purpose of human life, known as Purushartha, is to discard Preya (the path of worldly joy) and honor Shreya (the path of salvation). To fulfill this purpose, one must first strengthen their intellect to understand where Shreya truly lies. As Chapter 17 explains, once this understanding is established, a person must then actively struggle and resist the obstacles that will inevitably arise on this path. This requires firm human effort, likened to the steadfastness of Dattatreya. It is not a passive process but a conscious and determined struggle to choose wisdom over ignorance and long-term spiritual well-being over short-term worldly pleasures.
