KENA UPANISHAD · 2/5

इह चेदवेदीदथ सत्यमस्ति न चेदिहावेदीन्महती विनष्टिः ।
भूतेषु भूतेषु विचित्य धीराः प्रेत्यास्माल्लोकादमृता भवन्ति ॥

iha cedavedīdatha satyamasti na cedihāvedīnmahatī vinaṣṭiḥ ।
bhūteṣu bhūteṣu vicitya dhīrāḥ pretyāsmāllokādamṛtā bhavanti ॥

If here one comes to that knowledge, then one truly is; if here one comes not to the knowledge, then great is the perdition. The wise distinguish That in all kinds of becomings and they pass forward from this world and become immortal.
