Can you explain the philosophical concept presented in Chapter 37 about why Brahman can appear as something other than what it is?

Chapter 37 delves into a profound philosophical point about perception and reality. It states that a single divine principle, Brahman, pervades everything in existence, from the creator Brahma down to the smallest blade of grass. This principle is inherently devoid of worldly qualities. However, as Chapter 37 explains, when it is combined with adjuncts, or 'upadhis,' it can appear to be something other than Brahman to a soul deluded by ignorance. This delusion of separateness is what leads an individual to mistakenly believe that they are different from the Parabrahman, which in turn subjects them to the cycle of rebirth.
