According to the provided text, what is the simplest and most accessible method for attaining the supreme goal in the current age?

In Chapter 3, the text outlines that different ages have had different primary spiritual practices. While past ages like Kruta and Treta focused on 'control of mind and senses' and 'sacrifice' respectively, the current Kali Age offers a more accessible path. The simple means for achieving the supreme goal (Paramartha) is described as 'singing the stories of the Name.' This method is universally available to all four castes, from Brahmins onwards, as well as women, Shudras, and those of low caste. The core of this practice is listening to the stories of the Guru, which is presented as an easy and powerful means for all seekers.
