Ramayana 2.34.57

न मे तथा पार्थिव धीयते मनोमहत्सु कामेषु न चात्मनःप्रिये।यथा निदेशे तव शिष्टसम्मतेव्यपैतु दुःखं तव मत्कृतेऽनघ।।।।

na me tathā pārthiva dhīyate mano mahatsu kāmeṣu na cātmanoḥ priye | yathā nideśe tava śiṣṭasammate vyapaitu duḥkhaṃ tava matkṛte 'nagha ||

O king, my mind finds no such contentment in great pleasures or in what is dear to me as it does in carrying out your command, approved by the wise. Let your sorrow on my account pass away, O blameless one.
