Explain the significance of studying Sai's life story in the Kali Yuga as compared to practices in other ages.

Chapter 3 establishes the study of Sai's life story as the paramount spiritual practice for the current age, the Kali Yuga. The text explicitly states that the spiritual goals attained in previous eras through different means—'meditation' in the Kruta Age, 'sacrifice' in the Treta Age, and 'worship' in the Dwapara Age—are all achievable in the Kali Age through the simpler path of 'singing the Name' and service to the Guru. The author declares his intention to take this "straight path: the study of Sai’s life story" over other devotional acts like building temples or going on pilgrimages. This highlights the unique accessibility and power of devotion to Sai for attaining liberation in contemporary times.
