Bhagavad Gita · 3.31

ये मे मतमिदं नित्यमनुतिष्ठन्ति मानवाः।श्रद्धावन्तोऽनसूयन्तो मुच्यन्ते तेऽपि कर्मभिः॥

ye me matam idaṁ nityam anutiṣhṭhanti mānavāḥ śhraddhāvanto 'nasūyanto muchyante te 'pi karmabhiḥ

Those who always follow this teaching of Mine with faith and without envy are freed from the bondage of karma.
