yam āhur asya sthiti-janma-saṃyamaṃ tribhir vihīnaṃ yam anantam ṛṣayaḥ /
na veda siddhārtham iva kvacit sthitaṃ bhū-maṇḍalaṃ mūrdha-sahasra-dhāmasu //

21. “Salutation (I bow) to that Lord whom ‘Rishayah’ (Lakshmi and the Vedas) proclaim to be the cause of the existence, creation, and destruction of this Universe, but to be himself not subject to these three states and to be unlimited and to be one who does not feel to be even like a mustard seed, this world located somewhere among the spaces on His thousand heads.
