युगपत्सर्वदेवीभिर्दिधित्सुर्जाह्नवीं सुतः / षण्मुखान्यसृजच्छ्रीमांस्तेनायं षण्मुखः स्मृतः
yugapatsarvadevībhirdidhitsurjāhnavīṃ sutaḥ / ṣaṇmukhānyasṛjacchrīmāṃstenāyaṃ ṣaṇmukhaḥ smṛtaḥ
The son of Jāhnavī, wishing to be borne at once by all the Goddesses, created six radiant faces; therefore he is remembered as Ṣaṇmukha, the Six‑faced Lord.
