KAṬHA UPANISHAD · 1.1.10

शान्तसंकल्पः सुमना यथा स्याद्
वीतमन्युर्गौतमो माऽभि मृत्यो ।
त्वत्प्रसृष्टं माऽभिवदेत्प्रतीत
एतत् त्रयाणां प्रथमं वरं वृणे ॥ १०॥

śāntasaṃkalpaḥ sumanā yathā syād
vītamanyurgautamo mā’bhi mṛtyo ।
tvatprasṛṣṭaṃ mā’bhivadetpratīta
etat trayāṇāṃ prathamaṃ varaṃ vṛṇe ॥ 10॥

“Tranquillised in his thought and serene of mind be the Gautama, my father, let his passion over me pass away from him; assured in heart let him greet me from thy grasp delivered; this boon I choose, the first of three.”

Sri Aurobindo · CWSA 18, p. 103
