What does Chapter 16 say about why a perfect being like the Sadguru takes on a human body?

According to Chapter 16, the Sadguru is described as stainless, imperishable, and beyond attributes—an ocean of Truth, Consciousness, and Bliss whose own desires are always fulfilled. Despite this perfection, the chapter clarifies the purpose of his physical form. It states that the King of Yogis has 'taken this body for the sake of helping others, to uplift the poor and lowly.' Furthermore, it mentions that by 'donning the cloak of ignorance, He imparts knowledge to the ignorant,' using his human form to give sweet instruction without transgressing the boundaries of proper conduct, thus making spiritual knowledge accessible to all.
