Aditi’s Payo-vrata and Viṣṇu’s Promise to Appear as Her Son
Prelude to Vāmana
त्वयार्चितश्चाहमपत्यगुप्तये पयोव्रतेनानुगुणं समीडित: । स्वांशेन पुत्रत्वमुपेत्य ते सुतान् गोप्तास्मि मारीचतपस्यधिष्ठित: ॥ १८ ॥
tvayārcitaś cāham apatya-guptaye payo-vratenānuguṇaṁ samīḍitaḥ svāṁśena putratvam upetya te sutān goptāsmi mārīca-tapasy adhiṣṭhitaḥ
You have prayed to Me and properly worshiped Me by performing the great payo-vrata ceremony for the sake of protecting your sons. Because of Kaśyapa Muni’s austerities, I shall agree to become your son and thus protect your other sons.
In this verse, the Lord says Aditi’s payo-vrata (a devotional vow centered on worship while subsisting on milk) properly pleased Him, leading Him to personally arrange protection for her children by taking birth as her son.
Because Aditi worshiped Him with devotion specifically for protecting her offspring; the Lord, satisfied by her vow and prayers, promises to accept sonship through His plenary expansion to safeguard her sons.
It teaches that sincere, disciplined devotional practice and prayer for righteous purposes invite divine support—cultivating steadiness, faith, and a protective spiritual atmosphere for one’s family.
