Bāṣkala Upaniṣad 9

mama pratiṣṭhā bhuva āṇḍakośā vi caimi saṃ ca hi nu yo virapśī /
ahaṃ nv ahiṃ parvate śiśriyāṇam ugro nu kaṃ tavasāvasyur addhā //9//

My foundations are the worlds, the egg-shells; I disperse and I gather together, I who am exuberant. / I indeed [struck down] the serpent resting on the mountain, fierce indeed, for the sake of the strong one seeking help, in truth. //9
