According to Chapter 3 of Sai Satcharitra, what is the simplest way to achieve the supreme goal in the current age of Kali Yuga?

Chapter 3 explains that while different ages had different prescribed methods for spiritual attainment, the Kali Age offers a uniquely simple path. In the Kruta Age, it was control of the mind; in the Treta Age, sacrifice; and in the Dwapara Age, worship. However, for the current Kali Age, the text emphasizes that "singing the stories of the Name" is the easy means for the supreme goal, or Paramartha. This method, specifically listening to the stories of the Guru, is described in Chapter 3 as a universal path accessible to all four castes, as well as women and those of low caste, requiring no great exertion beyond focused attention.
