सुपर्णमीशं पततामथाश्वराजानमुच्चैःश्रवसं चकार सिंहं मृगाणां वृषभं गवां च प्लक्षं पुनः सर्ववनस्पतीनाम् //
suparṇamīśaṃ patatāmathāśvarājānamuccaiḥśravasaṃ cakāra siṃhaṃ mṛgāṇāṃ vṛṣabhaṃ gavāṃ ca plakṣaṃ punaḥ sarvavanaspatīnām //
He appointed Suparṇa (Garuḍa) as lord of the birds, and Uccaiḥśravas as king of horses. He made the lion foremost among beasts, the bull foremost among cattle, and the plakṣa tree foremost among all trees.
It reflects creation and cosmic ordering (sarga): the divine establishes hierarchy by appointing chief beings (adhipatis) for classes of creatures and plants, indicating structured governance of nature rather than dissolution.
By analogy, it models righteous governance: just as the Creator assigns fit leaders for each domain, a king or householder should maintain order by placing capable guardians/overseers in appropriate roles and upholding harmony among dependents.
No direct Vāstu or ritual rule is stated; however, such “foremost” lists (e.g., plakṣa among trees) often inform ritual selection of auspicious materials/woods in later Puranic practices and temple-related traditions.
