Rig Veda 10.183

apaśyaṃ tvā manasā cekitānaṃ tapaso jātaṃ tapaso vibhūtam iha prajām iha rayiṃ rarāṇaḥ pra jāyasva prajayā putrakāma

I saw thee meditating in thy spirit what sprang from Fervour and hath thence developed. Bestowing offspring here, bestowing riches, spread in thine offspring, thou who cravest children.

apaśyaṃ tvā manasā dīdhyānāṃ svāyāṃ tanū ṛtvye nādhamānām upa mām uccā yuvatir babhūyāḥ pra jāyasva prajayā putrakāme

I saw thee pondering in thine heart, and praying that in due time thy body might be fruitful. Come as a youthful woman, rise to meet me: spread in thine offspring, thou who cravest children.

ahaṃ garbham adadhām oṣadhīṣv ahaṃ viśveṣu bhuvaneṣv antaḥ aham prajā ajanayam pṛthivyām ahaṃ janibhyo aparīṣu putrān

In plants and herbs, in all existent beings I have deposited the germ of increase. All progeny on earth have I engendered, and sons in women who will be hereafter.
