Why does Chapter 8 of the Sai Satcharitra describe the human body in such a negative and graphic way?

Chapter 8 of the Sai Satcharitra describes the physical body in stark terms to emphasize its transient and impure nature, thereby encouraging a focus on the eternal spirit. The text calls the body a "washroom of excrement and urine" and a "foul place of phlegm, pus, and saliva." It highlights that death is a constant possibility at every moment, calling this a "great misfortune." This perspective, detailed in the chapter, is not meant to be simply negative but to serve a philosophical purpose: to detach the seeker from an over-identification with the physical form and to underscore that the body is not the true self, contrasting this decaying vessel with the eternal goal of realizing the Supreme Self.
