The Yoga of Action

Krishna concludes Chapter 3 with the secret of conquering desire. Know yourself as buddheḥ param—the Self beyond intellect. From there, steady the mind through saṁstabhyātmānam ātmanā—using pure awareness to control the restless self. Then slay kāma-rūpam, desire itself. Why does this work when willpower fails? Because you're not fighting desire from within it (impossible), but watching it from beyond (durāsadam—difficult, but possible from Self-awareness).
