The scripture says a single principle pervades everything from the creator to a blade of grass. What prevents a person from realizing this truth?

Chapter 37 explains that a single, unified principle indeed pervades everything in existence, from the creator Brahma to the smallest blade of grass. The reason a person fails to perceive this universal truth is because they are a "soul deluded by ignorance." The text elaborates that this divine principle, which is inherently devoid of worldly qualities, becomes obscured when it is combined with adjuncts, or 'upadhis'. It is this combination, viewed through the filter of ignorance, that makes the unified reality appear as if it were not Brahman, thus creating a false sense of separation and multiplicity.
