"When a person shuts themselves inside the shell of their stubbornness, pride, and ego, then even the light of truth fails to reach their heart. Knowledge only shows its effect when the heart is willing to bow, and the learner feels themselves empty (humbled). But when someone becomes hell-bent only on proving their superiority, they do not let the truth win—they only make their ego win; and thus, knowledge, intellect, and understanding all lose."
