Bhagavad Gita 3.41

तस्मात्त्वमिन्द्रियण्यादौ नियमस्य भरतर्षभ |
पापमानं प्रजाहि ह्येनं ज्ञानविज्ञाननाशनम्

Translation

Therefore, O best of the Bharatas, in the very beginning bring the senses under control and slay this enemy called desire, which is the embodiment of sin and destroys knowledge and realization.
