Final answer:
Krishna advises Arjuna to perform his duty as a warrior because it aligns with his Dharma, advocating for action without attachment to the results to ensure societal order and spiritual growth.
Step-by-step explanation:
The reason Krishna gives Arjuna for urging him to perform his duty as a warrior is rooted in the teachings of the Bhagavad Gita, where Krishna represents the universal being and provides guidance on living and acting with wisdom. According to Krishna, it is Arjuna's duty (Dharma) as a Kshatriya (warrior caste) to fight in the battle, regardless of his personal connections or the emotions that he feels towards his opponents. As a charioteer, Krishna counsels Arjuna on various concepts including the nature of life and death, the self, and duty. The underlying message is to perform his own duty without attachment to results, which is important for spiritual growth and the upholding of societal order. This non-attachment is meant to lead Arjuna towards the path of righteousness and the realization of his true self, which is beyond the physical realm.
