Srimad-Bhagavatam: Canto 3 - Chapter 1 - Verse 2
ऋषिरुवाचमा खिदो राजपुत्रीत्थमात्मानं प्रत्यनिन्दिते ।भगवांस्तेऽक्षरो गर्भमदूरात्सम्प्रपत्स्यते ॥ २ ॥
ṛṣir uvācamā khido rāja-putrītthamātmānaṁ praty aninditebhagavāṁs te ’kṣaro garbhamadūrāt samprapatsyate
The sage said: Do not be disappointed with yourself, O princess. You are actually praiseworthy. The infallible Supreme Personality of Godhead will shortly enter your womb as your son.
Kardama Muni encouraged his wife not to be sorry, thinking herself unfortunate, because the Supreme Personality of Godhead, by His incarnation, was going to come from her body.
