Do thou perform (thy) bounden duty, for action is superior to inaction and even the maintenance of the body would not be possible for thee by inaction.

Do the action that is yours to do, for action is better than inaction. Without action, even the maintenance of your body would not be possible.

Krishna gives Arjuna a direct instruction: perform your prescribed action, niyataṃ karma, the duty that belongs to your role. Action is better than inaction. He adds a down-to-earth reason: without any action, one could not even keep the body alive. The verse answers Arjuna's opening question plainly. Whatever the value of knowledge, it does not cancel the need to act. Some traditions take niyata to mean regular religious duties, others the duties of one's station, but in context it clearly points to Arjuna's task as a warrior.
