Can you explain what is meant by 'ignorance personified' and its relationship to the ego?

In Chapter 50, the concept of 'ignorance personified' is directly linked to pride and the body-ego. The text poses the question: who would call a person wise if their body-ego has not been relinquished? It then states that the 'seat of pride' is the very name for 'ignorance personified.' This means that when a person is deeply identified with their physical body and holds a sense of pride and self-importance based on that identity, they are embodying the very principle of ignorance. This ego-centric pride obscures the reality that 'Brahman is Truth, Knowledge, and Infinity' and keeps one trapped in the confusion of Maya, preventing the brilliance of true knowledge from shining through.
