The first step is Karmayoga, the selfless sacrifice of works, and here the Gita’s insistence is on action. The second is Jnanayoga, the self-realisation and knowledge of the true nature of the self and the world; and here the insistence is on knowledge; but the sacrifice of works continues and the path of Works becomes one with but does not disappear into the path of Knowledge.
The last step is Bhaktiyoga, adoration and seeking of the supreme Self as the Divine Being, and here the insistence is on devotion; but the knowledge is not subordinated, only raised, vitalised and fulfilled, and still the sacrifice of works continues; the double path becomes the triune way of knowledge, works and devotion. And the fruit of the sacrifice, the one fruit still placed before the seeker, is attained, union with the divine Being and oneness with the supreme divine nature.
