What kind of worldly attachments are identified as obstacles to attaining true knowledge?

The texts clearly identify several worldly attachments that obscure true knowledge and keep a person in a state of ignorance. Chapter 50 points out that a person whose "mind is fixed on wealth and luxury, and is unsatisfied in sense enjoyment" has a knowledge that is merely ignorance. Furthermore, someone who is "constantly thinking of wife and sons" and is deluded by these attachments to money and family does not know their own welfare, even if they are otherwise considered 'wise'. The teachings from Chapter 50 emphasize that as long as a person is without devotion and entangled in these worldly concerns, their knowledge remains covered by ignorance, preventing the dawn of true 'Jnana' and the attainment of liberation.
