Karma Yoga has two aspects—knowledge and material ingredients. Of these two, the component of knowledge is superior to the component of material ingredients. Knowledge is the culmination of all actions and of everything else, accessories and other things helpful. This knowledge alone, which is to be obtained by all means, is practised as comprehended in Karma Yoga. And this knowledge being regularly practised, reaches gradually what is ultimately attainable i.e., the vision of the self.
