According to Chapter 3, what is the simplest spiritual path recommended for everyone in the current age, regardless of their background?

Chapter 3 explains that while previous ages had different prescribed duties, the current Kali Age offers a uniquely simple path to the supreme goal (Paramartha). This path is 'singing the stories of the Name,' specifically listening to the stories of the Guru. The text emphasizes its universal accessibility, stating, "For all four castes, from Brahmins onwards, the means is listening to the stories of the Guru. Whether woman, Shudra, or of low caste, it is one means for all." This practice is presented as an easy and powerful method to burn away sins and achieve liberation, requiring no complex rituals or exertions other than focused attention, making it suitable for every individual.
