How does the experience of suffering in worldly existence (Samsara) lead a person towards spiritual seeking, as described in Chapter 17?

Chapter 17 explains that the 'unfathomable wheel of worldly existence (Samsara) spins incessantly,' causing individuals to suffer from three unendurable torments. It is only after being exhausted by this 'extreme peak of sorrow' that a person begins to search for a way to stop this painful cycle. As this chapter narrates, when the thought arises about how to stop the wheel's rotation, true 'Purushartha' (human effort for a worthy goal) is born. This suffering, therefore, acts as a catalyst, motivating the individual to investigate and choose the successful means for their own true self-interest, which is the path of Shreya, or salvation.
