Based on the source text from Chapter 12, what is the relationship between saints, the Supreme Soul, and worldly existence?

Chapter 12 of the Sai Satcharitra posits a profound connection between saints and the divine. It describes saints as being like "Agastya (who drank the ocean) for the ocean of worldly existence," meaning they help souls overcome the vast challenges of mortal life. They are also likened to the "sun for the darkness of ignorance." Crucially, the text asserts that the Supreme Soul resides right within them and that saints are, in reality, inseparable from Him. This implies that saints are not merely messengers but are direct manifestations of the Supreme Soul, incarnated to guide humanity.
