विहाय कामान्यः सर्वान्पुमांश्चरति निःस्पृहः। निर्ममो निरहङ्कारः स शान्तिमधिगच्छति॥
vihaya kaman yah sarvan pumamsh charati nihsprihah nirmamo nirahankarah sa shantim adhigacchati
Translation
That person who, giving up all desires, moves about free from longing, without a sense of ownership and free from egoism — that person attains peace.
Commentary
Three poisons that destroy peace: desire (sprha), possessiveness (mama), and ego (ahamkara). Freedom from these three brings the unshakeable peace that Arjuna is searching for.
