The concept of the 'Self' in Chapter 37 is described as 'Unqualified'. What does this mean?

Chapter 37 provides a profound description of the Self, or the 'Unqualified' (Nirguna). It is explained as the true essence that is beyond the intellectual concepts of 'existence' and 'non-existence'. This Self is devoid of all specific qualities; it is without sound, form, taste, or smell and is described as being beyond birth, death, and old age. The text emphasizes that the Self is eternal, unborn, ancient, and all-pervading like the sky. Crucially, we are warned not to mistake this formless nature for being a 'void' or non-existent. This is a form of ignorance that must be dispelled through knowledge.
