Can you provide a summary of the societal conditions that necessitate the advent of a saint as described in Chapter 4?

Chapter 4 of the Sai Satcharitra details a number of specific societal and moral degradations that call for a saint's incarnation. These conditions include Brahmins despising their own caste while Shudras attempt to become Brahmins, a general disrespect for religious teachers, and a state where everyone considers themselves a scholar without genuine wisdom. Furthermore, the text mentions a breakdown of conduct, where people ignore rules about what should be eaten or served, and even Brahmins consume liquor and meat openly. The chapter also points to growing sectarian hatred, a weariness among spiritual practitioners with their daily rituals, and a general obsession with wealth, status, and family as the only sources of happiness, all of which signal the time for a saint to appear.
