Matsya Purana — Account of the Manvantaras: Manus
अरुणस् तत्त्वदर्शी च वित्तवान्हव्यपः कपिः युक्तो निरुत्सुकः सत्त्वो निर्मोहो ऽथ प्रकाशकः //
aruṇas tattvadarśī ca vittavānhavyapaḥ kapiḥ yukto nirutsukaḥ sattvo nirmoho 'tha prakāśakaḥ //
He is Aruṇa, radiant; a seer of truth, possessed of wealth, a performer of havya-oblations, and swift like a monkey; disciplined and serene, unagitated, established in sattva-purity, free from delusion—indeed, a bringer of illumination.
It does not describe Pralaya directly; instead, it lists inner virtues—truth-seeing, purity (sattva), and freedom from delusion—qualities valued for spiritual steadiness in any cosmic cycle.
It frames an ethical model: disciplined conduct (yukta), lack of greedy agitation (nirutsuka), ritual responsibility (havyapa), and clear judgment (tattvadarshi). These support just rule and balanced household life.
The ritual term "havya" points to Vedic oblations and sacrificial duty; while not Vāstu-specific, it reflects the Purāṇic emphasis that right ritual conduct and purity underpin sacred works.
