8.8.3

devarṣaya ūcuḥ |
ajāyātha sarvādipūjyāya nityaṃ nirālambaneti svarūpāya ḍhuṇḍhe |
sadā'vyaktarūpāya sarvāntagāya namo dhūmravarṇāya sarveśvarāya ||

The divine sages said: / To the unborn, to the one who is worshipped first of all, whose nature is eternally supportless, O Ḍhuṇḍhi, / to the one whose form is ever unmanifest, who reaches the end of all, homage to Dhūmravarṇa, the Lord of all!
