karṇastu vedanāṃ dhairyādasahyāṃ vinigṛhya tām |

Though the pain was intolerable, Karna bore it with heroic patience, and continued to hold Bhrigu's son on his lap, without quivering in the least and without manifesting any sign of pain. When at last Karna's blood touched the body of Rama of great energy, the latter awoke and said these words in fear, 'Alas, I have been made impure! What is this that thou art doing, Tell me, casting off all fear, what is the truth of this matter!' Then Karna informed him of that worm's bite. Rama saw that worm which resembled a hog in shape. It had eight feet and very keen teeth, and it was covered with bristles that were all pointed like needles. Called by the name of Alarka, its limbs were then shrunk (with fear). As soon as Rama cast his, eyes on it, the worm gave up its life-breath, melting in that blood which it had drawn. All this seemed wonderful. Then in the welkin was seen a Rakshasa of terrible form, dark in hue, of a red neck, capable of assuming any form at wilt, and staying on the clouds,--his object fulfilled, the Rakshasa, with joined hands, addressed Rama, saying, 'O best of ascetics, thou hast rescued me from this hell! Blessed be thou, I adore thee, thou hast done me good!' Possessed of great energy, the mighty-armed son of Jamadagni said unto him, 'Who art thou? And why also didst thou fall into hell? Tell me all about it.' He answered, 'Formerly I was a great Asura of the name of Dansa. In the Krita period, O sire, I was of the same age with Bhrigu.
