What does Chapter 3 say is the simplest way to achieve the supreme goal, especially in the current age?

Chapter 3 explains that while different ages have different prescribed methods for spiritual attainment, the simplest means for the supreme goal (Paramartha) in the current Kali Age is "singing the stories of the Name." The chapter emphasizes that listening to the stories of the Guru is a universal and easy path accessible to everyone, regardless of their caste or social standing, including Brahmins, women, and Shudras. This method is presented as a straightforward alternative to more complex spiritual practices.
