Concluding Chapter 16, Krishna gives Arjuna his final directive. Therefore (tasmāc), the scriptures must be accepted as the ultimate authority and evidence (śāstraṁ pramāṇaṁ te) in determining what must be done and what must not be done (kāryākārya-vyavasthitau). Having understood these authorized rules and regulations (jñātvā śāstra-vidhānoktaṁ), you should perform your actions in this world (karma kartum ihārhasi) to ensure your gradual spiritual elevation.
