Matsya Purana — Origins of Gods and Beings: Daksha’s Progeny
यदा तु सृजतस्तस्य देवर्षिगणपन्नगान् न वृद्धिम् अगमल्लोकस् तदा मैथुनयोगतः दक्षः पुत्रसहस्राणि पाञ्चजन्यामजीजनत् //
yadā tu sṛjatastasya devarṣigaṇapannagān na vṛddhim agamallokas tadā maithunayogataḥ dakṣaḥ putrasahasrāṇi pāñcajanyāmajījanat //
But when, even as he created the hosts of divine seers and the serpent-races, the world did not attain increase, then Dakṣa, through the discipline of procreative union, begot thousands of sons upon Pāñcajanyā.
It describes creation (sarga), not pralaya: when initial beings like divine seers and serpent-races did not sufficiently increase the world’s population, Dakṣa expands creation through procreative generation of many sons.
It supports the Purāṇic ideal that household life (gṛhastha) and regulated procreation are legitimate dharmic means for sustaining society—growth and continuity are achieved through disciplined, purposeful union rather than mere ascetic creation alone.
No direct Vāstu or temple-ritual rule is stated; the verse is genealogical/cosmogonic, emphasizing population increase through Dakṣa’s progeny rather than architectural prescriptions.
