How can I tell if my knowledge is genuine or just a form of ignorance?

Chapter 50 provides clear distinctions between genuine knowledge and what only appears to be knowledge. True knowledge, or 'Vidya,' is described as the eternal pulse of 'I am Brahman' and the realization that "I am the Soul, the pure witness; purely enlightened and liberated." In stark contrast, the text identifies a state of ignorance in those who may seem wise but are attached to worldly things. If a person's mind is fixed on wealth, luxury, and sense enjoyment, or is constantly thinking of their wife and sons, their knowledge is considered to be covered by ignorance. This lack of devotion and a self-perception as a "sinner, unfortunate, luckless" person are hallmarks of 'Avidya' (ignorance), not true knowledge.
