Based on Chapter 17, what must a person do to overcome suffering and embark on the path of true self-interest?

According to the teachings in Chapter 17, a person suffering from the unendurable torments of worldly existence (Samsara) must first search for a way to stop this cycle. When this thought arises, true manhood (Purushartha) is born. To embark on the path of true self-interest, one must choose Shreya (the Good) over Preya (the Pleasant). This requires strengthening the intellect and developing discrimination. The chapter advises that one must actively root out obstacles such as the desire for seen and unseen enjoyments, hope, thirst, and cravings. Ultimately, this struggle for the sake of Shreya is the true purpose of human life.
