According to Chapter 3 of Sai Satcharitra, what is the recommended spiritual practice for the current age (Kali Yuga), and how does it compare to practices of other ages?

Chapter 3 explains that different ages have different primary spiritual practices. In the Kruta Age, the focus was on controlling the mind and senses; in the Treta Age, it was sacrifice; and in the Dwapara Age, it was worship. For our current era, the Kali Age, the text highlights that "singing the stories of the Name" is the simple and accessible means for achieving the supreme goal. As detailed in this chapter, listening to the Guru's stories is a universal path available to all people, regardless of their caste or gender, making it the most suitable practice for this age.
