Matsya Purana — The Burning of Tripura and Rudra’s Victory
प्रासादाग्रेषु रम्येषु वनेषूपवनेषु च वातायनगताश्चान्याश् चाकाशस्य तलेषु च //
prāsādāgreṣu ramyeṣu vaneṣūpavaneṣu ca vātāyanagatāścānyāś cākāśasya taleṣu ca //
Some (female spirits or subtle beings) dwell upon the lovely tops of mansions, in forests and pleasure-groves; others abide in windows and openings, and still others move about in the open expanse of the sky.
This verse does not discuss Pralaya; it belongs to the Matsya Purana’s Vastu-oriented material, describing where unseen beings are believed to frequent, as part of omen-lore connected with dwellings and their surroundings.
For kings and householders, it supports the duty of maintaining auspicious residences—palaces, homes, and gardens—by understanding traditional śakuna (omen) teachings about spaces like rooftops and windows, which were treated as sensitive architectural zones.
Architecturally, it highlights key liminal areas—prāsāda-agra (roof/upper levels) and vātāyana (windows/openings)—as spiritually charged zones in Vastu Shastra, implying careful design, cleanliness, and protective rites for openings and elevated parts of buildings.
