Those who are alike in happiness and distress; who are established in the self; who look upon a clod, a stone, and a piece of gold as of equal value; who remain the same amidst pleasant and unpleasant events; who are intelligent; who accept both blame and praise with equanimity; who remain the same in honor and dishonor; who treat both friend and foe alike; and who have abandoned all enterprises – they are said to have risen above the three guṇas [material nature]. - 14.25
Here we have the traits of the truly detached, someone who doesn't allow even attachment - when it arises - to disturb his sense of equanimity. To be beyond the gunas is to be beyond the outcome of actions taken in the material universe, it does not mean to not act, as action is considered the highest form of situating oneself in the Supreme according to Krishna in the Bhagavad Gita.
