Bhagavad Gita 3.43

एवं बुद्धे: परं बुद्ध्वा संस्तभ्यात्मानमात्मना |
जहि शत्रुं महाबाहो कामरूपं दुरासदम

Translation

Thus knowing the soul to be superior to the material intellect, O mighty armed Arjun, subdue the lower self (senses, mind, and intellect) by the higher self (strength of the soul), and kill this formidable enemy called lust.
