Kaṭha Upaniṣad 5.15

5.15

na tatra sūryo bhāti na candratārakaṃ nemā vidyuto bhānti kuto 'yam agniḥ /
tam eva bhāntam anu bhāti sarvaṃ tasya bhāsā sarvam idaṃ vibhāti //

15. The sun shines not there, nor the moon and stars, These lightnings shine not, much less this (earthly) fire! After Him, as He shines, doth everything shine, This whole world is illumined with His light.

5.15.p1

// iti pañcamī vallī //

5.15.p2

ūrdhvamūlo avākśākha eṣo 'śvatthaḥ sanātanaḥ /
tad eva śukraṃ tad brahma tad evāmṛtam ucyate /
tasmiṃl lokāḥ śritāḥ sarve tad u nātyeti kaścana //

1. Its root is above, its branches below— This eternal fig-tree! That (root) indeed is the Pure. That is Brahma. That indeed is called the Immortal. On it all the worlds do rest, And no one soever goes beyond it. This, verily, is That!
