Bhagavad Gita · Chapter 4: Knowledge and the Renouncing of Action

Bhagavad Gita 4.22

yadṛcchālābhasantuṣṭo dvandvātīto vimatsaraḥ | samaḥ siddhāvasiddhau ca kṛtvāpi na nibadhyate ||

Content with whatever comes unsought, beyond the pairs of opposites, free from envy, and the same in success and failure, such a person is not bound even while acting.

Modern context

Four marks of a free person at work are listed here. They are content with what comes without grasping for more. They are not thrown about by pleasure and pain, praise and blame. They do not envy. They are steady in success and in failure. Envy stands out in the list because it is such a quiet poison. It takes another person's good fortune and turns it into one's own unhappiness, although nothing has been lost.
