sa raja-putro vavrdhe
asu sukla ivodupah
kasthabhir iva so ’nvaham
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
As the moon, in its waxing fortnight, develops day after day, so the royal prince [Pariksit] very soon developed luxuriantly under the care and full facilities of his guardian grandfathers.
