ऋषेस्तु वेदशिरसस्तुषिता नाम पत्न्यभूत् । तस्यां जज्ञे ततो देवो विभुरित्यभिविश्रुत: ॥ २१ ॥
ṛṣes tu vedaśirasas tuṣitā nāma patny abhūt tasyāṁ jajñe tato devo vibhur ity abhiviśrutaḥ
The renowned ṛṣi Vedaśirā had a wife named Tuṣitā, and from her womb was born the divine avatāra celebrated as Vibhu.
Vibhū is described here as a divine incarnation of the Lord, born from Tuṣitā, the wife of the sage Vedaśirā, and renowned by the name “Vibhū.”
He is listing the births and identities of the Lord’s incarnations connected with specific sages and their families as part of the Manvantara/avatāra descriptions.
It reinforces that the Supreme Lord can manifest in many ways and places, and that honoring sacred lineages and hearing about divine appearances strengthens faith and devotion.
