Bhagavad Gita 4.27 — Discipline lit by knowledge
सर्वाणीन्द्रियकर्माणि प्राणकर्माणि चापरे। आत्मसंयमयोगाग्नौ जुह्वति ज्ञानदीपिते ॥
sarvāṇīndriyakarmāṇi prāṇakarmāṇi cāpare | ātmasaṃyamayogāgnau juhvati jñānadīpite ||
Meaning
Others offer all the actions of the senses and of the life-breath into the fire of self-discipline, lit by knowledge.
