Translation:
The demons [Rākṣasas], the servants of Hiraṇyakaśipu, thus began striking the tender parts of Prahlāda Mahārāja’s body with their tridents. The demons all had fearful faces, sharp teeth and reddish, coppery beards and hair, and they appeared extremely threatening. Making a tumultuous sound, shouting, “Chop him up! Pierce him!” they began striking Prahlāda Mahārāja, who sat silently, meditating upon the Supreme Personality of Godhead.
