Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Sukadeva Gosvami said: O King, after Aditi was thus advised by her husband, Kasyapa Muni, she strictly followed his instructions without laziness and in this way performed the payo-vrata ritualistic ceremony.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
For advancement in anything, especially in spiritual life, one must strictly follow the bona fide instructions of the teacher. Aditi did this. She strictly followed the instructions of her husband and guru. As confirmed in the Vedic injunctions, yasya deve para bhaktir yatha deve tatha gurau. One should have complete faith in the guru, who helps the disciple make progress in spiritual life. As soon as the disciple thinks independently, not caring for the instructions of the spiritual master, he is a failure (yasyaprasadan na gatih kuto ’pi). Aditi very strictly followed the instructions of her husband and spiritual master, and thus she was successful.
