Matsya Purana — Ritual Bathing
सुकृतं दुष्कृतं चैव सर्वं पश्यसि सर्वग सत्यदेव नमस्ते ऽस्तु प्रसीद मम भास्कर //
sukṛtaṃ duṣkṛtaṃ caiva sarvaṃ paśyasi sarvaga satyadeva namaste 'stu prasīda mama bhāskara //
You behold all—both merit and demerit—O all-pervading One. O God of truth, salutations to You; be gracious to me, O Bhāskara (the Sun).
This verse does not describe pralaya directly; it emphasizes a moral-cosmic principle: the Sun, as an all-pervading witness, sees all actions (merit and sin), implying an ordered universe where karma is knowable and accountable.
By stating that sukṛta and duṣkṛta are fully seen by the divine witness (Sūrya), it reinforces ethical self-governance: a king must rule justly and a householder must act dharmically, knowing that hidden actions are still accountable.
Ritually, it functions as a Sūrya-prārthanā (sun prayer) seeking prasāda (grace). While no explicit Vāstu rule appears, such stotras commonly frame daily rites (e.g., sunrise worship) that accompany Purāṇic ritual discipline.
