Peace in the Gita is not escape. It is evenness — the same heart in praise and blame, gain and loss — because you have found what cannot be taken.
आपूर्यमाणमचलप्रतिष्ठं समुद्रमापः प्रविशन्ति यद्वत्। तद्वत्कामा यं प्रविशन्ति सर्वे स शान्तिमाप्नोति न कामकामी।।2.70।।
He attains peace into whom desires flow as rivers into the ocean, which, though brimming with water, remains ever the same; not he whom desires carry away.
विहाय कामान्यः सर्वान्पुमांश्चरति निःस्पृहः। निर्ममो निरहंकारः स शांतिमधिगच्छति।।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.
भोक्तारं यज्ञतपसां सर्वलोकमहेश्वरम्। सुहृदं सर्वभूतानां ज्ञात्वा मां शान्तिमृच्छति।।5.29।।
Knowing Me as the One who gladly receives all offerings of austerity and sacrifice, as the Mighty Ruler of all the Worlds and the Friend of all beings, he passes to Eternal Peace.
आरुरुक्षोर्मुनेर्योगं कर्म कारणमुच्यते। योगारूढस्य तस्यैव शमः कारणमुच्यते।।6.3।।
For the sage who seeks the heights of spiritual meditation, practice is the only method, and when they have attained it, they must maintain themselves there through continual self-control.
यथा दीपो निवातस्थो नेङ्गते सोपमा स्मृता। योगिनो यतचित्तस्य युञ्जतो योगमात्मनः।।6.19।।
The wise man who has conquered his mind and is absorbed in the Self is like a lamp that does not flicker, as it stands sheltered from every wind.
यतो यतो निश्चरति मनश्चञ्चलमस्थिरम्। ततस्ततो नियम्यैतदात्मन्येव वशं नयेत्।।6.26।।
When the volatile and wavering mind wanders, let him restrain it and bring it back to its allegiance to the Self.
यस्मान्नोद्विजते लोको लोकान्नोद्विजते च यः।हर्षामर्षभयोद्वेगैर्मुक्तो यः स च मे प्रियः।।12.15।।
He who does not harm the world, and whom the world cannot harm, who is not carried away by any impulse of joy, anger, or fear; such a one is My beloved.
ब्रह्मभूतः प्रसन्नात्मा न शोचति न काङ्क्षति।समः सर्वेषु भूतेषु मद्भक्तिं लभते पराम्।।18.54।।
When he unites with the Eternal and his soul knows the bliss of the Self, he feels no desire or regret, he regards all beings equally, and enjoys the blessing of supreme devotion to Me.
