Mantra 11

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

In plain words

The attainment of every desire, the foundation of the world, the endlessness of ritual power, the far shore of fearlessness, the great and far-famed praise -- having seen all this, Naciketas, being steady, cast it off with firm resolve.
