Who is speaking and story frame
जज्ञे त्वष्टुर्दक्षिणाग्नौ दानवीं योनिमाश्रित: ।
वृत्र इत्यभिविख्यातो ज्ञानविज्ञानसंयुत: ॥ ३८ ॥
jajñe tvaṣṭur dakṣiṇāgnau
dānavīṁ yonim āśritaḥ
vṛtra ity abhivikhyāto
jñāna-vijñāna-saṁyutaḥ
Being cursed by mother Durgā [Bhavānī, the wife of Lord Śiva], that same Citraketu accepted birth in a demoniac species of life. Although still fully equipped with transcendental knowledge and practical application of that knowledge in life, he appeared as a demon at the fire sacrifice performed by Tvaṣṭā, and thus he became famous as Vṛtrāsura.
