Renunciation and the actions, of the two which is not good (means both are good); but from renunciation of actions, Yog of performing actions is superior.
Note that Karma sanyas (renunciation of actions) is different from Sanyas (renunciation of fruits of action). While first is pessimistic rejection of all actions, latter is detachment from fruits of actions. Performing actions is superior to renunciation of actions, says Lord Kritsna.
