Matsya Purana — The Cave-Sanctuary: Jewel-Lake
इन्द्रनीलमहास्तम्भं मरकतासक्तवेदिकम् वज्रांशुजालैः स्फुरितं रम्यं दृष्टिमनोरमम् //
indranīlamahāstambhaṃ marakatāsaktavedikam vajrāṃśujālaiḥ sphuritaṃ ramyaṃ dṛṣṭimanoramam //
It had great pillars of sapphire (indranīla), an altar-platform inlaid with emeralds, and it glittered with a network of diamond-like rays—charming, and delightful to behold.
This verse is not about Pralaya; it focuses on sacred architectural splendor—pillars, altar-platforms, and radiant ornamentation—typical of the Matsya Purana’s Vastuvidya descriptions.
Indirectly, it supports the dharmic ideal that kings and householders patronize well-designed sacred spaces—beautifying temples/altars as an act of merit (puṇya) and public welfare through orderly, auspicious construction.
It highlights Vastu-aligned sacred aesthetics: indranīla pillars and a marakata-inlaid vedikā (altar/pedestal) that “glitters” with vajra-like radiance—imagery used to specify auspicious materials, elevated platforms, and visually sanctifying brilliance in temple or ritual structures.
