FAQs
It presents a unified cosmic order: time (seasons), governance (Lokapalas), lineage obligations (Pitrs), divine administration (Devas), and structured knowledge (64 vidyas) as interlinked realities pervading all three worlds.
By showing that all cosmic functions and all branches of knowledge operate within the same three-world order upheld by the divine, the verse frames learning and ritual duties as supports to a theistic life that culminates in devotion to the Supreme.
The verse points to systematic classification of vidyas—useful for organizing Vedanga-based study (e.g., śikṣā, vyākaraṇa, chandas, nirukta, jyotiṣa, kalpa) and applying it to ritual timing, duties to Pitrs, and dharmic conduct.
