Acharya Prashant explains that the conflict faced by Arjuna in the Bhagavad Gita is not a personal one but represents the universal struggle of all mankind. He clarifies that Shri Krishna and Arjuna are both within us, with Shri Krishna representing the heart or the core of one's being. Addressing the power to sing of greatness, he identifies this power as the human capacity for choice, free will, and doership. Man is a creature of choice who asserts his freedom through his decisions, and the ego functions as the primary decision-maker. The scriptures emphasize that the power to choose the truth or God lies entirely with the individual, and exercising this power vigilantly is essential to avoid choosing against the truth.
