Matsya Purana — Cosmography of Śākadvīpa and Successive Dvīpas: Mountains
यस्माद्विभ्राजते वह्निर् विभ्राजस्तेन स स्मृतः सैवेह केशवेत्युक्तो यतो वायुः प्रवाति च //
yasmādvibhrājate vahnir vibhrājastena sa smṛtaḥ saiveha keśavetyukto yato vāyuḥ pravāti ca //
Because fire shines forth (vibhrājate), he is remembered by the name Vibhrājas. And here he is also called Keśava, because from him the wind blows and moves.
It frames Vishnu as the underlying source of cosmic forces—fire’s radiance and wind’s motion—implying that even in cosmic transitions like pralaya, elemental powers function by his sustaining principle.
By linking divine order to the regulated workings of fire and wind, the verse supports the ethic that rulers and householders should uphold order through disciplined use of Agni (sacrifice, cooking, rites) and respect for Vayu (clean air, proper ventilation, regulated life-breath).
Ritually, it underscores Agni and Vayu as divinely grounded—supporting correct fire-ritual performance and reverence for the sacred fire. Architecturally (Vastu), it aligns with ensuring proper airflow (vāyu-pravāha) and correct placement/maintenance of fire spaces (kitchen, yajña-śālā) as part of sacred order.
