How does Chapter 17 link the experience of worldly suffering to the awakening of true human effort and the need for a Guru?

Chapter 17 of the Sai Satcharitra explains that the incessant spinning of the wheel of worldly existence (Samsara) causes man to suffer three unendurable torments (Tritapa). It is only after being exhausted by this extreme sorrow that a person begins to search for a way to stop the cycle. The chapter states that when this thought arises, by great fortune, true manhood or human effort (Purushartha) is born. However, the path is filled with obstacles like ignorance (Maya). This is why a Guru is essential; as the chapter highlights, the Guru can show the path to a place where even the intellect and the Vedas cannot enter, guiding the seeker beyond suffering.
