According to Chapter 4 of the Sai Satcharitra, what are the societal conditions that necessitate the incarnation of a saint?

Chapter 4 explains that a saint's incarnation becomes necessary when there is a significant decay of religion and morality. This includes times when Brahmins despise their own caste, religious teachers are insulted, and people disregard religious teachings, with everyone considering themselves a scholar. The chapter also mentions a rise in sectarian hatred, a loss of respect for others, and even Brahmins openly consuming liquor and meat. When people become obsessed with worldly happiness from wealth and family, turning away from the ultimate spiritual goal, and when religious practitioners grow tired of their duties, that is the time for a saint to descend to awaken religion.
