Can you detail the specific signs of societal decay that Chapter 4 identifies as the catalyst for a saint's advent?

Chapter 4 of the Sai Satcharitra provides a detailed list of societal problems that necessitate a saint's incarnation. These signs include Brahmins despising their own caste while Shudras try to become Brahmins, religious teachers being insulted, and a general disregard for religious teachings. The chapter also mentions a state where people compete with one another without respect, ignore proper conduct, and even Brahmins openly consume liquor and meat. Furthermore, sectarian hatred grows, and people become distressed, signaling the time for a saint to appear.
