Based on Chapter 16, what is the Sadguru's role in imparting knowledge, and how does He interact with the ignorant?

Chapter 16 explains that the Sadguru's purpose in taking a body is to help others and uplift the poor and lowly. His method for imparting knowledge is unique; the text says He dons "the cloak of ignorance" in order to give knowledge to the ignorant, suggesting He meets people at their own level. Furthermore, He provides "sweet instruction" without transgressing the proper boundaries of conduct. The chapter highlights that a disciple may not even be aware of their own pitfalls, but the Guru, in His wisdom, provides the necessary remedy. His speech itself is described as the "river of nectar from the ocean of Vedanta."
