Based on Chapter 17, why is a 'learned' person not necessarily wise, and what is required to find true peace?

Chapter 17 makes a clear distinction between being learned and being wise. The text questions the value of being 'learned' if a person is simultaneously 'wallowing in sinful deeds prohibited by the Vedas and Smritis' and cannot distinguish right from wrong. True wisdom is more than accumulated knowledge. The chapter further elaborates that one who is always restless, whose heart is unsatisfied, and whose mind is distracted by the greed of the senses will not find peace, even with extensive knowledge. Therefore, according to the teachings in Chapter 17, finding peace requires controlling tendencies like lust and anger and cultivating a calm, satisfied mind free from worldly cravings.
