Matsya Purana — Ila–Sudyumna Episode and the Expansion of the Ikṣvāku
अगमद् वडबारूपम् उत्तमं केन हेतुना ततस् तु मैत्रावरुणिं पप्रच्छुस्ते पुरोधसम् //
agamad vaḍabārūpam uttamaṃ kena hetunā tatas tu maitrāvaruṇiṃ papracchuste purodhasam //
“For what reason did (he/it) assume the excellent form of the Vaḍabā?” Then they questioned Maitrāvaruṇi, their family priest, about it.
It signals a cosmological inquiry: the “Vaḍabā-form” is treated as a significant transformation linked to cosmic forces often discussed around dissolution-era themes, prompting an authoritative explanation from a priestly sage.
It models dhārmic conduct: when confronted with complex metaphysical questions, one should consult qualified teachers (purohita/ṛṣi) rather than speculate—an ethic relevant to rulers and householders alike.
Direct Vāstu or temple-building rules are not stated; the ritual takeaway is the reliance on a purohita as the proper interpreter of sacred cosmology and its meanings within rites and teachings.
