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

Chapter 4 details the specific societal and moral decay that necessitates a saint's incarnation. These conditions include times when Brahmins despise their own caste while Shudras attempt to become Brahmins, when religious teachers are insulted, and when people ignore religious teachings. Further signs are the growth of sectarian hatred, people becoming distressed, and even spiritual practitioners like Brahmins, ritualists, and Yogis growing tired of their respective duties such as prayers, ceremonies, and meditation. Saints descend when people are lost, focusing only on worldly happiness from wealth, status, and family, thus turning away from the ultimate spiritual goal.
