SB 4.17.28
evam manyumayim murtim
krtantam iva bibhratam
pranata prañjalih praha
mahi sañjata-vepathuh
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
At this time Prthu Maharaja became exactly like Yamaraja, and his whole body appeared very angry. In other words, he was anger personified. After hearing him, the planet earth began to tremble. She surrendered, and with folded hands began to speak as follows.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The Supreme Personality of Godhead is death personified to miscreants and the supreme beloved Lord to the devotees. In Bhagavad-gita (10.34) the Lord says, mrtyuh sarva-haras caham: “I am all-devouring death.” Faithless unbelievers, who challenge the appearance of God, will be delivered by the Supreme Personality of Godhead when He appears before them as death. Hiranyakasipu, for example, challenged the authority of the Supreme Personality of Godhead, and the Lord met him in the form of Nrsimhadeva and killed him. Similarly, the planet earth saw Maharaja Prthu as death personified, and she also saw him in the mood of anger personified. Therefore she began to tremble. One cannot challenge the authority of the Supreme Personality of Godhead in any circumstance. It is better to surrender unto Him and take His protection at all times.
