The Upaniṣads / Kaṭha / 6.13 It is

6.13

The Kaṭha (कठ)

अस्तीत्येवोपलब्धव्यस् तत्त्वभावेन चोभयोः ।
अस्तीत्येवोपलब्धस्य तत्त्वभावः प्रसीदति
astīty evopalabdhavyas tattvabhāvena cobhayoḥ |
astīty evopalabdhasya tattvabhāvaḥ prasīdati

The line

It is to be taken just as 'it is,' and by the being-real of both. Of one who has taken it just as 'it is,' the reality settles clear.

नेपालीमा

यो छ भनेर नै लिनुपर्छ, र दुवैको वास्तविक भावले पनि। जसले यो छ भनेर नै लिएको छ, त्यसको वास्तविकता स्पष्ट बस्छ।

Where it sits

Ubhayoḥ (उभयोः) is both, the two sides of the grasp. The mantra does not rename them in this line. The next mantra is the falling away of desires.

Split: asti iti eva (अस्ति इति एव) + upalabdhavyam (उपलब्धव्यम्) + tattva-bhāvena ca (तत्त्व-भावेन च) + ubhayoḥ (उभयोः) + asti iti eva upalabdhasya (अस्ति इति एव उपलब्धस्य) + tattva-bhāvaḥ prasīdati (तत्त्व-भावः प्रसीदति)
