Who is speaking and story frame
सूतीगृहे ननु जगाद भवानजो नौ
सञ्जज्ञ इत्यनुयुगं निजधर्मगुप्त्यै ।
नानातनूर्गगनवद् विदधज्जहासि
को वेद भूम्न उरुगाय विभूतिमायाम् ॥ २० ॥
sūtī-gṛhe nanu jagāda bhavān ajo nau
sañjajña ity anu-yugaṁ nija-dharma-guptyai
nānā-tanūr gagana-vad vidadhaj jahāsi
ko veda bhūmna uru-gāya vibhūti-māyām

O supremely glorified, all-pervading Lord, who can understand the mystic, deluding potency of Your opulent expansions?
