Matsya Purana — The Tale of Brahmadatta: Past-life Memory
अहसत्तेन योगात्मा स पिपीलिकरागतः यत्र तत्कीटमिथुनं रममाणमवस्थितम् //
ahasattena yogātmā sa pipīlikarāgataḥ yatra tatkīṭamithunaṃ ramamāṇamavasthitam //
By the power of yogic subtlety, that yogin entered the state of an ant; and there he saw an insect-pair, stationed together, sporting in mutual delight.
Indirectly, it highlights yogic mastery over form and perception—an ability often emphasized in Purana narratives around Pralaya to show that consciousness can persist and observe even when gross conditions change.
It functions as a moral-psychological illustration: rulers and householders should recognize how desire operates even in small beings, cultivating restraint and discernment rather than being driven by instinctive impulses.
No direct Vastu or ritual procedure is stated; the verse is primarily yogic-narrative, using subtle transformation and observation as a teaching device rather than prescribing temple-building or rites.
