SB 4.24.13
pracinabarhisah putrah
satadrutyam dasabhavan
tulya-nama-vratah sarve
dharma-snatah pracetasah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
King Pracinabarhi begot ten children in the womb of Satadruti. All of them were equally endowed with religiosity, and all of them were known as the Pracetas.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The word dharma-snatah is significant, for the ten children were all merged in the practice of religion. In addition, they possessed all good qualities. One is supposed to be perfect when one is perfectly religious, perfect in the execution of one’s vows to render devotional service, perfect in knowledge, perfect in good behavior, and so on. All the Pracetas were on the same level of perfection.
