न हि ज्ञानेन सदृशं पवित्रमिह विद्यते |
तत्स्वयं योगसंसिद्ध: कालेनात्मनि विन्दति || 38||
na hi jñānena sadṛiśhaṁ pavitramiha vidyate
tatsvayaṁ yogasansiddhaḥ kālenātmani vindati
na hi jnanena sadrisham pavitramiha vidyate
tatsvayam yogasansiddhah kalenatmani vindati
BG 4.38: In this world, there is nothing as purifying as divine knowledge. One who has attained purity of mind through prolonged practice of Yog, receives such knowledge within the heart, in due course of time.
