Matsya Purana — Cosmic Creation: Emergence of the Great Elements and the Navel-Lotus
तस्य चिन्तयमानस्य निर्वाते संस्थिते ऽर्णवे निराकाशे तोयमये सूक्ष्मे जगति गह्वरे //
tasya cintayamānasya nirvāte saṃsthite 'rṇave nirākāśe toyamaye sūkṣme jagati gahvare //
As he was contemplating, the ocean lay windless and still; in that water-made, subtle, cavern-like state of the world—where even space seemed absent—everything remained contained in a withdrawn condition.
It depicts pralaya as a windless, motionless cosmic ocean where the world becomes subtle and withdrawn—so undifferentiated that “space” itself is described as absent or unmanifest.
Indirectly, it frames an ideal of inner steadiness: just as the ocean is “windless and settled,” a king or householder is urged in the Purana to cultivate composed reflection (cintā) before acting, especially in times of crisis or transition.
No direct Vāstu or ritual rule is stated; the verse instead supplies the cosmological baseline (dissolution into a water-like subtle state) that later Purāṇic ritual and temple symbolism often mirror—returning to stillness before re-manifestation.
