How does Chapter 22 explain the concept of illusion and the role of the Guru?

Chapter 22 uses a powerful metaphor to explain the nature of illusion and the Guru's role in it. It compares illusion to seeing a snake in dim light, when in reality, it is just a rope. The chapter states that the Sadguru is the 'creator of the snake-like tendency' and also 'the one who gives it the form of a rope.' This means the Guru is the source of both the illusion (maya) and the reality behind it. Ultimately, the Guru is the one who removes the fear born from this illusion. As Chapter 22 explains, the Guru is the 'form of knowledge' and the 'destroyer of the fear of worldly existence,' guiding devotees from the darkness of misperception into the light of truth.
