52.24

brahmādīnāṃ paraṃ dhāma trayāṇāmapi saṃsthitiḥ
vedamūrtāv ataḥ pūṣā pūjanīyaḥ prayatnataḥ //

He who has adored all the four (Brahmâ, Sûrya, Viṣṇu and Śiva) without observing any difference among them, has worshipped, in fact, the whole universe, including the moveable and the immoveable.—23. He who is the supreme abode of Brahmâ and the rest, in whom all the three (Vedas) reside, He is Pûṣam, the personification of Vedas; and consequently he should be worshipped with great diligence.—24.
