Ramayana
अस्मिन्नेवाभिसम्प्राप्तं लोके विदितमस्तु ते । विभीषणवचः श्रुत्वा राक्षसेन्द्रः स रावणः । दौरात्म्येनात्मनोद्धूतस्तप्ताम्भ इव सागरः ॥ 7-25-29 ॥
Know that this has befallen you in this very world. Hearing the words of Vibhishana, Ravana, that lord of the Rakshasas, agitated by his own evil nature, was like the ocean with its waters heated to boiling.
