According to the teachings, what qualities define a person who is truly endowed with knowledge?

As described in Chapter 17, a person truly endowed with knowledge is defined not by academic learning but by their inner state and conduct. The primary quality is a satisfied mind and an unwavering focus on the Self. Such a person is referred to as a well-behaved "son of the Guru," indicating discipline and dedication. This is contrasted with someone who may be "learned" but remains restless, unsatisfied, and distracted by sensory greed, who cannot find peace. Chapter 17 stresses that practice is the essence, not mere talk; the knowledgeable person is the master of the "chariot of the body," capable of restraining the senses and maintaining a calm mind.
