Bhagavad Gita 2.71
He attains peace who, giving up desire, moves through the world without aspiration, possessing nothing that he can call his own and is free from pride.
विहाय कामान्यः सर्वान्पुमांश्चरति निःस्पृहः।
निर्ममो निरहंकारः स शांतिमधिगच्छति॥vihāya kāmānyaḥ sarvānpumāṃścarati niḥspṛhaḥ|
nirmamo nirahaṃkāraḥ sa śāṃtimadhigacchati||
