Kaṭha Upaniṣad 6.2

6.2

yad idaṃ kiṃca jagat sarvaṃ prāṇa ejati niḥsṛtam /
mahad bhayaṃ vajram udyataṃ ya etad vidur amṛtās te bhavanti //

2. This whole world, whatever there is,
Was created from and moves in Life (prāṇa).
The great fear, the upraised thunderbolt—
They who know That, become immortal.
3. From fear of Him fire (Agni) doth burn.
From fear the sun (Sūrya) gives forth heat.
From fear both Indra and Wind (Vāyu),
And Death (Mṛityu) as fifth, do speed along.
