According to Chapter 3 of Sai Satcharitra, what is the simplest path to the supreme goal in the current Kali Age, and who is it available to?

Chapter 3 of the Sai Satcharitra explains that while previous ages had different means for salvation—such as control of the senses in the Kruta Age, sacrifice in the Treta, and worship in the Dwapara—the Kali Age offers a much simpler path. For our current era, 'singing the stories of the Name' is presented as the easy means for achieving the supreme goal, or Paramartha. This chapter strongly emphasizes that this path is universally accessible. It is not restricted by social standing or gender, as it is explicitly stated to be the one means for all four castes from Brahmins onwards, as well as for women, Shudras, and those of low caste. The primary requirement is a meritorious desire to listen.
