Unenlightened does not realize the reality. It still thinks i am this body and mind. Enlightened person engages in all activities, whatever is necessary,. while maintaining brahma rishti, equal, non dual vision at all moments. Not that he's trying to think. I must think it is all bramman. The eighteenth verse. Seeing inaction in the midst of all activity, many agarma yopaset. At the level of brahman, artman, i do not do anything the real life. But tremendous activity can go on in my life if necessary. Can remain immersed in peaceful meditation also. So all activities are fully compatible with complete non activity.
