How does the text compare the path of devotion in the Kali Yuga to previous ages, and what specific path does the author choose to follow?

Chapter 3 draws a clear distinction between the devotional practices of different ages. It states that the spiritual states attained in the Kruta Age by 'meditation,' in the Treta Age by 'sacrifice,' and in the Dwapara Age by 'worship,' can all be achieved in the current Kali Age simply through 'singing the Name' and service to the Guru. This highlights a more accessible path to spiritual realization. While acknowledging that other devotees might build temples, go on pilgrimages, or perform kirtan, the author declares his own chosen path. As mentioned in Chapter 3, he decides to 'take the straight path: the study of Sai’s life story,' which he was commanded to write.
