How does Chapter 52 explain the concept of delusion and the path from the form (Saguna) to the formless (Nirguna)?

Chapter 52 delves into the philosophical concept of delusion, defining it as false knowledge or the pride of the Self in that which is not the Self. This error is identified as the root of all calamities, including the cycle of birth and death. To overcome this, the chapter explains the importance of meditating on Sai's physical form (Saguna). It states that without first entering the Saguna, the light of the formless Self (Nirguna) cannot be known, as the attributeless Parabrahma is otherwise very difficult to understand. Thus, meditating on Sai's form allows the subtle nature of the true Self to manifest as the attachment to the form eventually vanishes.
