Bhagavad Gita 12.17

यो न हृष्यति न द्वेष्टि न शोचति न काङ्क्षति।शुभाशुभपरित्यागी भक्ितमान्यः स मे प्रियः॥

yo na hṛṣyati na dveṣṭi na śocati na kāṅkṣati |śubhāśubhaparityāgī bhakिtamānyaḥ sa me priyaḥ ||

He who neither rejoices nor hates, nor grieves nor desires, renouncing both good and evil, and who is full of devotion, is dear to Me.

He who is beyond joy and hate, who neither laments nor desires, to whom good and evil fortunes are the same, such a one is beloved to Me.

Our plain-language meaning of this verse is waiting for scholar review.
