सा प्रहृष्टा वचः श्रुत्वा खरस्य वदनाच्च्युतम्।
प्रशशंस पुनर्मौर्ख्याद्भ्रातरं रक्षसां वरम्॥
sā prahṛṣṭā vacaḥ śrutvā kharasya vadanāc cyutam
praśaśaṁsa punar maurkhyād bhrātaraṁ rakṣasāṁ varam

Upon hearing the words coming out of the mouth of Khara, she became delighted and again foolishly praised her brother, the best of the rākṣasas.
