In Sermon (217), Imam Ali (a.s.) elaborates on the attributes of a pious and God-fearing person. This sermon was delivered during a time when the Islamic community faced various challenges, and there was a decline in the moral and spiritual state of the people. Through this sermon, the Imam emphasizes the importance of keeping one's intellect alive and the necessity of controlling the self.

The Imam states that a believer keeps his intellect alive and kills his self, meaning that he gains mastery over his desires and passions. This process elevates the individual spiritually. When a person conquers his self, his body also becomes light and healthy, symbolizing a balance between spiritual and physical well-being.

The Imam further explains that when a believer's intellect awakens, a bright light of guidance shines before him. This light leads him to a straight path. Various gates push him towards safety and tranquility, indicating that choosing the right path brings peace and comfort to one’s life.

A significant moral lesson from this sermon is the need for individuals to awaken their intellect and control their desires. This practice not only aids in spiritual growth but also positively impacts physical health. Imam Ali (a.s.) teaches us that true success is achieved when we harness our inner strengths in the right direction, leading to a fulfilling and peaceful life.
