SB 10.2.14
sandistaivam bhagavata
tathety om iti tad-vacah
pratigrhya parikramya
gam gata tat tathakarot
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Thus instructed by the Supreme Personality of Godhead, Yoga-maya immediately agreed. With the Vedic mantra om, she confirmed that she would do what He asked. Thus having accepted the order of the Supreme Personality of Godhead, she circumambulated Him and started for the place on earth known as Nanda-gokula. There she did everything just as she had been told.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
After receiving the orders of the Supreme Personality of Godhead, Yoga-maya twice confirmed her acceptance by saying, “Yes, sir, I shall do as You order,” and then saying om. Srila Visvanatha Cakravarti Thakura comments that om signifies Vedic confirmation. Thus Yoga-maya very faithfully received the Lord’s order as a Vedic injunction. It is a fact that whatever is spoken by the Supreme Personality of Godhead is a Vedic injunction that no one should neglect. In Vedic injunctions there are no mistakes, illusions, cheating or imperfection. Unless one understands the authority of the Vedic version, there is no purpose in quoting sastra. No one should violate the Vedic injunctions. Rather, one should strictly execute the orders given in the Vedas. As stated in Bhagavad-gita (16.24):
tasmac chastram pramanam te
karyakarya-vyavasthitau
jñatva sastra-vidhanoktam
karma kartum iharhasi
“One should understand what is duty and what is not duty by the regulations of the scriptures. Knowing such rules and regulations, one should act so that one may gradually be elevated.”
