What obstacles to attaining knowledge and peace are identified in the source material?

Chapter 17 identifies several significant obstacles to attaining knowledge and inner peace. It explicitly states that the tendencies of lust and anger are highly disruptive, as they instantly interfere with the crucial spiritual practices of listening, contemplation, and meditation. Furthermore, a mind that is always restless, unsatisfied, and distracted by the greed of the senses will not find peace, even if one possesses intellectual knowledge. The text also points to desires for seen and unseen enjoyments, hope, and cravings as fundamental obstacles that must be thoroughly uprooted. A person who is constantly engaged in sinful deeds is also unable to benefit from learning, lacking the basic discrimination between right and wrong.
