Bhagavad Gita 6.7

जितात्मनः प्रशान्तस्य परमात्मा समाहितः।शीतोष्णसुखदुःखेषु तथा मानापमानयोः॥

jitātmanaḥ praśāntasya paramātmā samāhitaḥ |śītoṣṇasukhaduḥkheṣu tathā mānāpamānayoḥ ||

The Supreme Self of him who is self-controlled and peaceful remains balanced in cold and heat, pleasure and pain, as well as in honor and dishonor.

The Self of one who is self-controlled and has attained peace is equally unmoved by heat or cold, pleasure or pain, honor or dishonor.

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