Bhagavad Gita Chapter 4, Verse 21

निराशीर्यচित्तः सर्वत्र समबुद्धिर्यश्चारितः | सिद्धिं सिद्धिं प्राप्य बुद्धिमान्स मां प्राप्य सिद्धिमवाप्नोति ||

nirāśīr yac-cittaḥ sarvatra sama-buddhir yaś cārjitaḥ siddhiṁ siddhiṁ prāpya buddhimān sa māṁ prāpya siddhim avāpnoti

One who has abandoned all desires, whose mind is content, who is free from longing, who has given up the sense of ownership, such a person attains peace.

Krishna describes another quality of the wise person. 'Nirāśīḥ' (free from desires/expectations) means not craving what one doesn't have. 'Sama-buddhiḥ sarvatra' (equal-minded everywhere) means balanced intelligence in all situations—not elated by success, not dejected by failure. The phrase 'siddhiṁ siddhiṁ prāpya' (having obtained success) shows the person achieves material success naturally, but 'buddhimān' (wise) means they understand these are temporary. The result: 'māṁ prāpya siddhim avāpnoti' (attains Me, attains perfection)—they reach the ultimate goal. This verse shows that peace and material success aren't contradictory—the wise person can have both, but isn't attached to either.
