KAṬHA UPANISHAD · 1.2.11

कामस्याप्तिं जगतः प्रतिष्ठां
क्रतोरानन्त्यमभयस्य पारम् ।
स्तोममहदुरुगायं प्रतिष्ठां दृष्ट्वा
धृत्या धीरो नचिकेतोऽत्यस्राक्षीः ॥ ११॥

kāmasyāptiṃ jagataḥ pratiṣṭhāṃ
kratorānantyamabhayasya pāram ।
stomamahadurugāyaṃ pratiṣṭhāṃ dṛṣṭvā
dhṛtyā dhīro naciketo’tyasrākṣīḥ ॥ 11॥

When thou hast seen in thy grasp, O Nachiketas, the possession of desire and firm foundation of this world and an infinity of power and the other shore of security and praise and scope and wide moving and firm foundation, wise and strong in steadfastness thou didst cast these things from thee.

Sri Aurobindo · CWSA 18, p. 110
