Matsya Purana — Marks of Karma-yoga and the Five Great Daily Sacrifices
ब्रह्मादीनां परं धाम त्रयाणामपि संस्थितिः वेदमूर्ताव् अतः पूषा पूजनीयः प्रयत्नतः //
brahmādīnāṃ paraṃ dhāma trayāṇāmapi saṃsthitiḥ vedamūrtāv ataḥ pūṣā pūjanīyaḥ prayatnataḥ //
Pūṣan is the supreme abode of Brahmā and the other gods, and the very support in which the three are established as well. Since he is embodied as the Veda itself, Pūṣan should therefore be worshipped with earnest effort.
Indirectly, it emphasizes cosmic stability (saṃsthiti) by identifying Pūṣan as a foundational support; it is not a direct Pralaya verse but frames divine order as upheld through the Veda-embodied solar principle.
It presents a dharmic duty of worship: rulers and householders should honor Pūṣan diligently, because aligning with the Veda (veda-mūrti) is portrayed as sustaining right order and prosperity.
Ritually, it authorizes Pūṣan’s special veneration as Veda-embodied, supporting temple and household puja sequences where solar deities are worshipped for nourishment, stability, and right order.
