What's the difference between the pure, formless Brahman and the 'qualified' Brahman mentioned in the text?

As detailed in Chapter 50, the pure Brahman is described as 'Chinmatra,' meaning it is purely the form of Consciousness, clean, and distinct from the expressed world. This is its ultimate, unmixed state. In contrast, the 'qualified' (shabal) Brahman is the same Brahman but associated with Avidya, or ignorance. This association makes it 'graspable by the intellect' and allows it to be expressed as 'Sat' (Existence) and meditated upon through the 'Omkar'. The text stresses that this qualified Brahman is different from the target, pure Brahman, and that spiritual practice involves moving aside the veils of ignorance to realize the original, unqualified Consciousness.
