Matsya Purana — Uma’s Austerities and the Slaying of the Deceiver Asura ĀḌi
तं दृष्ट्वा गिरिशस्तुष्टस् तदालिङ्ग्य महासुरम् मन्यमानो गिरिसुतां सर्वैरवयवान्तरैः //
taṃ dṛṣṭvā giriśastuṣṭas tadāliṅgya mahāsuram manyamāno girisutāṃ sarvairavayavāntaraiḥ //
Seeing him, Girīśa (Śiva) was pleased; and, embracing that mighty asura, he regarded him—through every limb and feature—as none other than the Daughter of the Mountain (Pārvatī) herself.
This verse does not discuss pralaya or cosmology; it focuses on Śiva’s pleased response and affectionate embrace within a Shaiva narrative episode.
Indirectly, it highlights a Purāṇic ethic: seeing the divine in others and responding with compassion or grace—an attitude that supports righteous conduct (dharma) for rulers and householders alike.
No explicit Vāstu/temple-rule detail appears in this verse; its ritual takeaway is devotional—Śiva’s favor and the sanctity of perceiving the Goddess (Girisutā) in form and presence.
