According to Chapter 3, what is the simplest spiritual path for people in the current age, and who is eligible to follow it?

Chapter 3 of Sai Satcharitra explains that while previous ages required difficult practices like mind control or sacrifice, the simplest path to the supreme goal in the current Kali Age is "singing the stories of the Name." This chapter emphasizes that listening to the stories of the Guru is the primary means for spiritual progress. A key teaching highlighted in this section is its universal accessibility; it is a path open to all four castes, from Brahmins to Shudras, as well as women and those of low caste. As mentioned in Chapter 3, this single means is available for everyone to burn away sins and find liberation.
