Bhagavad Gita 2.56

दुःखेष्वनुद्विग्नमनाः सुखेषु विगतस्पृहः।वीतरागभयक्रोधः स्थितधीर्मुनिरुच्यते॥

duḥkheṣvanudvignamanāḥ sukheṣu vigataspṛhaḥ |vītarāgabhayakrodhaḥ sthitadhīrmunirucyate ||

He whose mind is not shaken by adversity, who does not long for pleasures, and is free from attachment, fear, and anger, is called a sage of steady wisdom.

The sage whose mind is unruffled in suffering, whose desire is not aroused by enjoyment, who is without attachment, anger, or fear—take him to be one who stands at a lofty level.

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