Bhagwad Gita
Chapter 4, Verse 27
सर्वाणीन्द्रियकर्माणि प्राणकर्माणि चापरे।
आत्मसंयमयोगाग्नौ जुह्वति ज्ञानदीपिते।।4.27।।
Those who are interested in self-realization, in terms of mind and sense control, offer the functions of all the senses, as well as the vital force [breath], as oblations into the fire of the controlled mind.
