Matsya Purana — Brahmā’s Four Faces
एवम् उक्तास् ततः सर्वे ससृजुर् विविधाः प्रजाः गतेषु तेषु सृष्ट्यर्थं प्रणामावनताम् इमाम् //
evam uktās tataḥ sarve sasṛjur vividhāḥ prajāḥ gateṣu teṣu sṛṣṭyarthaṃ praṇāmāvanatām imām //
Thus instructed, all of them then brought forth diverse kinds of creatures; and when they had departed for the purpose of creation, this one remained bowed down in reverent obeisance.
It describes sarga (creation): once instructed, the agents of creation generate diverse beings and proceed to carry out creation—this is a post-instruction, world-populating moment rather than a pralaya description.
The emphasis is on obedience to rightful instruction and humility (praṇāma). In Purāṇic ethics, rulers and householders are likewise expected to act on dharmic counsel and maintain reverence toward divine order and teachers.
No vastu/temple-rule is stated directly; the ritual motif present is praṇāma (reverent salutation), a foundational act of worship and respectful conduct that precedes many rites.
