Matsya Purana — Division of Bhārata-varṣa
पद्मगन्धाश्च जायन्ते तत्र सर्वे च मानवाः जम्बूफलरसाहारा अनिष्पन्दाः सुगन्धिनः //
padmagandhāśca jāyante tatra sarve ca mānavāḥ jambūphalarasāhārā aniṣpandāḥ sugandhinaḥ //
There, all human beings are born with the fragrance of lotus-flowers. They live on the juice of jambu-fruit; they are steady and unshaken, and they are naturally sweet-smelling.
This verse does not describe Pralaya directly; it gives a cosmographic portrait of a region where humans are depicted as naturally pure and steady, suggesting an idealized post-creation order rather than dissolution.
Indirectly, it presents an ideal of human conduct—steadiness (aniṣpanda) and purity (sugandha)—which aligns with the ethical aim of self-control and sattvic living expected of householders and encouraged by righteous kings.
No explicit Vastu or temple-building rule appears here; the lotus-fragrance and natural purity imagery is more symbolic, often resonating with ritual ideals of cleanliness, auspicious scent, and sattvic sustenance.
