Matsya Purana — War of Devas and Dānavas: Yama and Kubera Defeated; Kālanemi’s Māyā and the A...
दैत्यास्तां वृष्टिमासाद्य समाश्वस्तास्ततः क्रमात् बीजाङ्कुरा इवाम्लानाः प्राप्य वृष्टिं धरातले //
daityāstāṃ vṛṣṭimāsādya samāśvastāstataḥ kramāt bījāṅkurā ivāmlānāḥ prāpya vṛṣṭiṃ dharātale //
When those Dāityas encountered that rainfall, they gradually regained their strength and composure—like seed-sprouts on the earth that, having received rain, are no longer withered.
It highlights the restorative phase after Pralaya: rain becomes a sign of renewed vitality, bringing even the Dāityas back to strength, like sprouts revived by water.
Indirectly, it teaches a governance-and-household ethic: timely nourishment and protection (symbolized by life-giving rain) restore stability and morale gradually—order returns step by step (kramāt).
No direct Vāstu or ritual rule is stated; the key takeaway is symbolic—water/rain as a purifier and life-restorer, a common principle underlying many purification rites (snāna, abhiṣeka) rather than a building prescription.
