Matsya Purana — Planetary Chariots
*सूत उवाच ताराग्रहाणां वक्ष्यामि स्वर्भानोस्तु रथं पुनः अथ तेजोमयः शुभ्रः सोमपुत्रस्य वै रथः //
*sūta uvāca tārāgrahāṇāṃ vakṣyāmi svarbhānostu rathaṃ punaḥ atha tejomayaḥ śubhraḥ somaputrasya vai rathaḥ //
Sūta said: “I shall describe the stars and planets, and again the chariot of Svarbhānu (Rāhu). Now, the chariot of Soma’s son is radiant—made of light—and brilliant white.”
This verse is not about Pralaya; it belongs to a cosmological-astronomical passage describing celestial bodies and the symbolic “chariots” of grahas such as Rāhu and Budha.
Indirectly, such Jyotiṣa-style descriptions support timekeeping and auspicious calendrical awareness used by kings and householders for rites, governance decisions, and ritual scheduling, though no explicit dharma-duty is stated here.
No Vāstu rule is stated, but the imagery (radiant, white, light-formed chariot) aligns with ritual-visual symbolism used in graha worship and in iconographic contemplation within Purāṇic ritual contexts.
