How does Avidya, or ignorance, manifest in a person's life and what is the consequence of this?

Avidya manifests as a deep-seated delusion and attachment to the material world. As Chapter 50 illustrates, this includes the false identification 'I am the body, mine are wife and home.' It also appears as great intellectual pride, where one thinks, 'Skilled in scriptures, possessing genius, there is no other equal to me.' This great pride becomes a cause for dissatisfaction. Those entangled in the ropes of thirst for sons, cattle, and other possessions may call themselves wise, but the text states they lack even a trace of true happiness.
