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

Chapter 3 explains that the prescribed spiritual path varies with the age, or Yuga. In the Kruta Age, the path was 'control of mind and senses'; in the Treta Age, it was 'sacrifice'; and in the Dwapara Age, 'worship' was the means. However, for the current Kali Age, the text emphasizes that 'singing the stories of the Name' is the simplest and most effective means for attaining the supreme goal. This chapter highlights that listening to the stories of the Guru is a universal path accessible to everyone, from Brahmins to Shudras and women, requiring only focused attention rather than the strenuous efforts of other practices.
