तज्ज्ञस्य संकटे च मुदितैव केवलं ज्योत्स्नेव भुवनभावमलंकरोति येन चित्तादृते तु ज्ञः कुर्वन्न प्यकर्ता संपन्नो मनसोऽलेपकत्वान्नासौ पादपा ण्यादिविक्षेपस्य यत्नकृतस्यापि कर्मणः फलमनुभवति ॥ १५ ॥ tajjñasya saṃkaṭe ca muditaiva kevalaṃ jyotsneva bhuvanabhāvamalaṃkaroti yena cittādṛte tu jñaḥ kurvanna pyakartā saṃpanno manaso'lepakatvānnāsau pādapā ṇyādivikṣepasya yatnakṛtasyāpi karmaṇaḥ phalamanubhavati ।

तज्ज्ञस्य संकटे च मुदितैव केवलं ज्योत्स्नेव
भुवनभावमलंकरोति येन चित्तादृते तु ज्ञः कुर्वन्न
प्यकर्ता संपन्नो मनसोऽलेपकत्वान्नासौ पादपा
ण्यादिविक्षेपस्य यत्नकृतस्यापि कर्मणः फलमनुभवति ॥ १५ ॥

15. He who knows the self, remains joyous even in his calamity, and shines as the moonlight, which enlightens the world. He knows that it is his mind and not his self, that is the agent of his actions although he is the doer of them: and knowing the agency of the mind in all his actions, he does not assume to himself the merit of the exercise of his limbs, hands and feet, nor expects to reap the rewards of all his assiduous labours and acts.
