Matsya Purana — Pṛthu
*सूत उवाच वंशे स्वायम्भुवस्यासीद् अङ्गो नाम प्रजापतिः मृत्योस्तु दुहिता तेन परिणीता सुदुर्मुखा //
*sūta uvāca vaṃśe svāyambhuvasyāsīd aṅgo nāma prajāpatiḥ mṛtyostu duhitā tena pariṇītā sudurmukhā //
Sūta said: In the lineage of Svāyambhuva (Manu) there was a Prajāpati named Aṅga. He married Sudurmukhā, the daughter of Mṛtyu (Death).
This verse does not describe Pralaya directly; it contributes to the Matsya Purana’s creation-era framework by mapping the early progenitor lineages (Prajāpatis) that populate the world after creation.
By presenting sanctioned lineage and marriage alliances among primordial beings, the verse reinforces the Purāṇic ideal that social order and dharma are maintained through proper marriage (vivāha) and continuity of progeny—principles later applied to householders and royal dynasties.
No direct Vāstu, temple-building, or ritual procedure is stated in this verse; it functions as genealogical narration setting context for later dharma and ritual sections.
