According to Chapter 3, who is eligible to listen to the Guru's stories, and how does this practice compare to the spiritual disciplines of other eras?

Chapter 3 emphasizes that listening to the Guru's stories is a universal means for spiritual attainment, accessible to all. It explicitly states that this path is for everyone, from Brahmins to women, Shudras, and those of low caste. This contrasts sharply with the prescribed practices of previous eras mentioned in the chapter: 'control of mind and senses' in the Kruta Age, 'sacrifice' in the Treta Age, and 'worship' in the Dwapara Age. In the current Kali Age, the simple act of hearing the Guru's stories is presented as the most effective means for the supreme goal, available to anyone with merit and a desire to listen.
