What is the simplest path to spiritual attainment in the Kali Age as described in Chapter 3?

According to Chapter 3, while other ages required more rigorous practices like 'control of mind and senses' or 'sacrifice', the Kali Age offers a much simpler means for attaining the supreme goal. This easy path is 'singing the stories of the Name,' specifically listening to the stories of the Guru. The text emphasizes that this method is universally accessible and is considered one means for all, regardless of their social standing, including Brahmins, women, Shudras, and those of low caste. No great exertion is needed, only focused attention.
