Bhagwad Gita
Chapter 3, Verse 43
एवं बुद्धेः परं बुद्ध्वा संस्तभ्यात्मानमात्मना।
जहि शत्रुं महाबाहो कामरूपं दुरासदम्।।3.43।।
Thus knowing oneself to be transcendental to material senses, mind and intelligence, one should control the lower self by the higher self and thus - by spiritual strength - conquer this insatiable enemy known as lust.
