Matsya Purana — The Greatness and Procedure of the Aṅgāra
पुरा दक्षविनाशाय कुपितस्य तु शूलिनः अथ तद्भीमवक्त्रस्य स्वेदबिन्दुर्ललाटजः //
purā dakṣavināśāya kupitasya tu śūlinaḥ atha tadbhīmavaktrasya svedabindurlalāṭajaḥ //
Long ago, when the trident-bearing Lord (Śiva) was enraged for the destruction of Dakṣa, then from the forehead of that One of dreadful countenance there arose a bead of sweat.
It does not describe Pralaya directly; it depicts a mythic moment of divine wrath where a physical emanation (a sweat-drop from Rudra’s forehead) becomes the seed for subsequent manifestation in the Dakṣa-sacrifice narrative.
By implication it warns that arrogance and sacrificial pride (as associated with Dakṣa in this episode) invite downfall; rulers and householders are urged to perform rites with humility and due honor to all deities and sacred persons.
The verse is ritual-mythic rather than architectural; its ritual takeaway is that yajña and worship must be conducted with correct reverence—otherwise the rite becomes spiritually defective and leads to destructive consequences.
