Chapter 3, Verse 43
Part of 3: Karm Yog — कर्मयोगएवं बुद्धेः परं बुद्ध्वा संस्तभ्यात्मानमात्मना। जहि शत्रुं महाबाहो कामरूपं दुरासदम्॥
evaṁ buddheḥ paraṁ buddhvā sanstabhyātmānam ātmanā jahi śhatruṁ mahā-bāho kāma-rūpaṁ durāsadam
Thus, knowing Him who is superior to the intellect and restraining the self by the Self, slay thou, O mighty-armed Arjuna, the enemy in the form of desire, hard to conquer.
Restrain the lower self by the higher Self. Subdue the lower mind by the higher mind. It is difficult to coner desire because it is of a highly complex and incomprehensible nature. But a man of discrimination and dispassion who does constant and intense Sadhana can coner it ite easily. Desire is the ality of Rajas. If you increase the Sattvic ality in you, you can coner desire. Rajas cannot stand before Sattva. Even though desire is hard to coner, it is not impossible. The simple and direct method is to appeal to the Indwelling Presence (God) through prayer and Japa. Thus in the Upanishads of the glorious Bhagavad Gita, the science of the Eternal, the scripture of Yoga, the dialogue between Sri Krishna and Arjuna, ends the third discourse entitledThe Yoga of Action.
