Acharya Prashant explains that while other scriptures like the Upanishads may be philosophically clearer, the Bhagavad Gita is unparalleled in its utility and impact due to its practical, real-life setting. Unlike the Upanishads, where the disciple is already willing and seeking knowledge in an idyllic environment, the Gita features a resistant and reluctant disciple, Shri Krishna's student Arjun. This resistance makes the Gita highly relatable to the common man, as Arjun faces worldly dilemmas involving attachment, fear, and social conditioning that mirror modern struggles.
