Matsya Purana — The Rite of Donating the ‘Mountain of Salt’
उत्तमः षोडशद्रोणैः कर्तव्यो लवणाचलः मध्यमः स्यात्तदर्धेन चतुर्भिरधमः स्मृतः //
uttamaḥ ṣoḍaśadroṇaiḥ kartavyo lavaṇācalaḥ madhyamaḥ syāttadardhena caturbhiradhamaḥ smṛtaḥ //
A salt-mound (Lavaṇācala) of the best grade should be made with sixteen droṇas; the middling grade is made with half of that; and the inferior grade is traditionally stated to be made with four (droṇas).
Nothing directly—this verse is technical and prescriptive, giving graded quantities for preparing a salt-heap using the droṇa measure, typical of Vastu/ritual procedural sections rather than Pralaya narration.
It reflects the duty to follow śāstric standards in public works, temple maintenance, and household/royal rituals—ensuring correct, graded provisioning of materials (here, salt) according to prescribed measures.
It specifies a Vastu/ritual standard for preparing a ‘lavaṇācala’ (salt mound/heap) in three grades (uttama, madhyama, adhama) using fixed droṇa quantities, emphasizing precision in construction/rite-related material preparation.
