Who is speaking and story frame
सञ्जातकोप: स्फुरितारुणाधरं
सन्दश्य दद्भिर्दधिमन्थभाजनम् ।
भित्त्वा मृषाश्रुर्दृषदश्मना रहो
जघास हैयङ्गवमन्तरं गत: ॥ ६ ॥
sañjāta-kopaḥ sphuritāruṇādharaṁ
sandaśya dadbhir dadhi-mantha-bhājanam
bhittvā mṛṣāśrur dṛṣad-aśmanā raho
jaghāsa haiyaṅgavam antaraṁ gataḥ
Being very angry and biting His reddish lips with His teeth, Kṛṣṇa, with false tears in His eyes, broke the container of yogurt with a piece of stone. Then He entered a room and began to eat the freshly churned butter in a solitary place.
