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

Chapter 3 of the Sai Satcharitra explains that different ages have had different primary spiritual practices. For instance, the Kruta Age emphasized 'control of mind and senses,' the Treta Age focused on 'sacrifice,' and the Dwapara Age centered on 'worship.' However, for the current Kali Age, the text identifies 'singing the stories of the Name' as the simple and most effective means for achieving the supreme goal. As described in this chapter, this practice, particularly listening to the stories of the Guru, is presented as a universal path accessible to all, including all four castes, women, and those of low caste, making it a uniquely inclusive method for spiritual liberation.
