एवं बुद्धेः परं बुद्ध्वा संस्तभ्यात्मानमात्मना |
जहि शत्रुं महाबाहो कामरूपं दुरासदम् ||३- ४३||
Oh! Arjuna, knowing that which is superior to the intellect in this way, having made the mind steady with the buddhi, destroy the enemy, that is in the form of desire, that which is so difficult to understand.
ॐ तत्सदिति श्रीमद्भगवद्गीतासूपनिषत्सु
ब्रह्मविद्यायां योगशास्त्रे श्रीकृष्णार्जुनसंवादे
कर्मयोगो नाम तृतीयोऽध्यायः ||३||
Thus in the Upanishads of the glorious Bhagavad Geeta, in the science of the Eternal, in the scripture of yoga, in the dialoge between Shri Krishna and Arjuna, the third discourse ends entitled Karma Yoga.
