Matsya Purana — Manifestation of Kauśikī
एवमुत्सृष्टशपाया गिरिपुत्र्यास्त्वनन्तरम् निर्जगाम मुखात्क्रोधः सिंहरूपी महाबलः //
evamutsṛṣṭaśapāyā giriputryāstvanantaram nirjagāma mukhātkrodhaḥ siṃharūpī mahābalaḥ //
Thus, immediately after the mountain-born goddess had released her curse, her wrath sprang forth from her mouth—taking the form of a powerful lion.
This verse is not about Pralaya; it illustrates instantaneous divine manifestation—wrath becoming a tangible force—showing how cosmic powers can externalize into forms within Purāṇic myth.
Indirectly, it warns that rash speech and provoked anger have immediate, forceful consequences; a king or householder is urged in Purāṇic ethics to restrain krodha (anger) and avoid actions that trigger destructive outcomes in society and family.
No Vāstu or temple-building rule is stated here; the ritual takeaway is symbolic—anger is treated as a potent, almost ritualized force in Purāṇic storytelling, emphasizing the need for śānti (appeasement) and restraint after a curse or intense emotion.
