According to Chapter 4, what are the specific societal conditions that signal the need for a Saint's incarnation?

Chapter 4 of the Shri Sai Satcharitra details the specific circumstances that call for a Saint's incarnation. These conditions arise when society is in a state of decay, such as when Brahmins despise their own caste, religious teachers are insulted, and people ignore religious teachings. Furthermore, it is a time of growing sectarian hatred, when people become distressed, and even Brahmins neglect their daily prayers and openly consume forbidden items like liquor and meat. It is to correct such widespread irreligion and atrocities committed under the cloak of religion that Saints descend to the mortal world.
