They dwell in ignorance, themselves believing they are wise and erudite, wandering erratically like the blind led by a blind man.

This verse offers a penetrating critique of pseudo-knowledge. Many consider themselves paṇḍitas (erudite) and dhīrāḥ (wise) while remaining deeply immersed in avidyā (ignorance). The result is that, believing they see, they fall into even deeper pits. The image of the blind leading the blind is a universal metaphor about the importance of finding a truly enlightened guru. In yoga, this underscores that it is not enough to accumulate intellectual information about sacred texts; a direct transformation of consciousness is required.
