KAṬHA UPANISHAD · 1.3.2
यः सेतुरीजानानामक्षरं ब्रह्म यत् परम् ।
अभयं तितीर्षतां पारं नाचिकेतँ शकेमहि ॥ २॥
yaḥ seturījānānāmakṣaraṃ brahma yat param ।
abhayaṃ titīrṣatāṃ pāraṃ nāciketam̐ śakemahi ॥ 2॥
May we have strength to kindle Agni Nachiketas, for he is the bridge of those who do sacrifice and he is Brahman supreme and imperishable, and the far shore of security to those who would cross this ocean.
Sri Aurobindo · CWSA 18, p. 114
