Bhagavad Gita 3.18
He has nothing to gain from the performance or non-performance of action; his welfare does not depend on any contribution that an earthly creature can make.
नैव तस्य कृतेनार्थो नाकृतेनेह कश्चन।
न चास्य सर्वभूतेषु कश्िचदर्थव्यपाश्रयः॥naiva tasya kṛtenārtho nākṛteneha kaścana|
na cāsya sarvabhūteṣu kaśicadarthavyapāśrayaḥ||
