"The Gita uses the word ‘karma’ (action) in the sense of swadharma. We eat, drink, sleep; these are all actions. But these are not the actions that the Gita refers to when it talks of karma. Karma refers to the performance of swadharma. But in order to attain desirelessness through such karma, an important aid is necessary. One must overcome desire, attachment and anger. One cannot have desirelessness unless and until the mind has become pure and calm like the waters of the Ganga. The actions necessary for the purification of mind are called vikarma by the Gita. Karma, vikarma and akarma—these three terms are important... Karma means the outward actions done in the pursuit of swadharma. Vikarma means total involvement of the mind therein."
