The text mentions that even a 'wise' person can be ignorant. What does it mean by this?

Chapter 50 presents a practical, behavioral definition of ignorance that transcends mere intellect. It suggests that a person, even if considered 'wise' by worldly standards, remains in a state of ignorance if their mind is fixated on wealth and luxury, and they are unsatisfied in sense enjoyment. The text is quite specific, stating that someone constantly thinking of their wife and sons, deluded by these attachments, does not know their own true welfare. This form of ignorance is linked to a lack of devotion, which is said to cover one's knowledge and prevent genuine spiritual progress.
