According to the text, what specific societal conditions necessitate the arrival of a saint on Earth?

Chapter 4 outlines several dire societal conditions that precipitate a saint's incarnation. These include times when Brahmins despise their own caste, religious teachers are insulted, and sectarian hatred grows. The text also points to a general disregard for religious principles, with people in every house considering themselves scholars and competing with one another. Furthermore, as Chapter 4 describes, a saint's advent is needed when Brahmins openly consume forbidden things like liquor and meat, and spiritual practitioners like yogis and ritualists grow tired of their practices. When people prioritize wealth and family over the ultimate spiritual goal, saints incarnate to awaken religion.
