sa ittham loka-guruna
sirasa jagrhe hareh
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The great saint Maitreya continued: My dear Vidura, in this way Maharaja Prthu, the conqueror of the entire world, accepted the instructions of the Supreme Personality of Godhead on his head.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
One should accept the instructions of the Supreme Personality of Godhead by bowing down at the lotus feet of the Lord. This means that anything spoken by the Personality of Godhead should be taken as it is, with great care and attention and with great respect. It is not our business to amend the words of the Supreme Personality of Godhead or make additions or alterations, as it has become a custom for many so-called scholars and svamis who comment on the words of Bhagavad-gita. Here the practical example of how to accept the instruction of the Supreme Personality of Godhead is shown by Prthu Maharaja. This is the way to receive knowledge through the parampara system.
