According to Chapter 4 of Sai Satcharitra, what specific societal and religious conditions necessitate the incarnation of a saint?

Chapter 4 of the Sai Satcharitra explains that a saint's incarnation is necessary when society faces significant moral and spiritual decay. This includes times when Brahmins despise their own caste, religious teachers are insulted, and people ignore the words of religion, with everyone considering themselves a scholar. The chapter further details that saints appear when people ignore proper conduct, Brahmins openly consume liquor, sectarian hatred grows, and even dedicated practitioners like yogis and ritualists grow tired of their spiritual duties, signaling a deep need for divine intervention.
