Matsya Purana — The Slaying of Jambha and the Rise of Tāraka: Divine Battle Formations
वायव्यास्त्रबलेनाथ निर्धूते मेघमण्डले बभूव विमलं व्योम नीलोत्पलदलप्रभम् //
vāyavyāstrabalenātha nirdhūte meghamaṇḍale babhūva vimalaṃ vyoma nīlotpaladalaprabham //
Then, O Lord, when the mass of clouds had been blown away by the power of the Vāyavya Astra (the wind-weapon), the sky became spotless and clear—shining with the hue of blue lotus petals.
It depicts a post-turbulence moment: the cloud-mass is dispersed by a divine wind-weapon, and the cosmos appears purified—suggesting restoration of clarity after a disruptive phase often associated with pralaya-like upheaval.
By analogy, it highlights the dharmic ideal of removing obscuration (confusion, disorder) to restore clarity—mirroring a king’s duty to re-establish order and a householder’s duty to maintain purity and steadiness in daily life.
While not a direct Vāstu rule, the verse emphasizes cleansing and clear space—an idea echoed in ritual and temple practice where purification (śuddhi) and unobstructed, luminous environments are prerequisites for consecration and worship.
