Acharya Prashant explains that Shri Krishna's smile in the Bhagavad Gita symbolizes detachment and the realization that nothing is truly at stake because the core of one's being, the Atma, remains untouched by worldly events. He contrasts Shri Krishna's state of unconditional okay-ness with Arjun's self-pity and misplaced associations. Arjun's misery stems from a lack of understanding of his true self and his proper relationship with the world. The speaker emphasizes that wisdom consists of knowing that all relationships in the material world are not ends in themselves but are means to the final goal of liberation. A wise person does not grieve for the living or the dead because they are centered in the truth and recognize that worldly objects and people only deserve attention or emotion based on their utility in the quest for spiritual freedom. Acharya Prashant further clarifies that being simple means simply seeing things as they are without the stubbornness of ignorance. He defines a wise man as one who uses all relationships with nature for the sake of the Atma. If a relationship brings one closer to liberation, it is a matter of satisfaction; if it causes one to sink deeper into worldly attachment, it is a matter of concern. Shri Krishna scolds Arjun for mourning those who do not deserve it, implying that his relatives were not assisting his spiritual progress. The speaker concludes that every action of a wise person, whether laughing, weeping, or fighting, is centered on the truth. The right relationship with any object or person is determined by whether it serves the purpose of liberation, even if that relationship manifests as conflict or war.
