Mantra 2

यः सेतुरीजानानामक्षरं ब्रह्म यत्परम् ।अभयं तितीर्षतां पारं नाचिकेतꣳ शकेमहि ॥ २ ॥

In plain words

He who is a bridge for those who perform sacrifice, the imperishable Brahman that is supreme -- may we be able [to know] that, the far shore of fearlessness for those who wish to cross over: the Nāciketa [fire and its teaching].
