Śrī Kāmākṣī–Mahātripurasundarī: Immanence of Śakti and Cosmic Administration
Lalitopākhyāna
तयोरेव समुत्पन्नो भैरवः क्रोधसंयुतः / मूर्धानमेकं चिच्छेद नखेनैव तदा विधेः / हाहेति तत्र सर्वे ऽपि क्रन्दन्तश्च पलायिताः
tayoreva samutpanno bhairavaḥ krodhasaṃyutaḥ / mūrdhānamekaṃ ciccheda nakhenaiva tadā vidheḥ / hāheti tatra sarve 'pi krandantaśca palāyitāḥ
From those two arose Bhairava, charged with wrath; then, with his nail alone, he severed one head of Vidhe (Brahmā). All there cried “Hā! Hā!”, weeping as they fled.
