सप्तपञ्चाशः सर्गः — Hanumān’s Return, Roar of Success, and the Announcement “Sītā Seen”
स पूरयामास कपिर्दिशो दश समन्ततः।।।।नदन्नादेन महता मेघस्वनमहास्वनः।
sa pūrayāmāsa kapir diśō daśa samantataḥ | nadannādēna mahatā mēghasvana-mahāsvanaḥ ||
Roaring with a mighty sound like the thunder of storm-clouds, the monkey filled all ten directions on every side.
The thundering noise of Hanuman filled all the ten directions with great sound.
Transparent communication in duty: the roar functions as an announcement—Dharma includes making one’s successful return and readiness to report known to allies.
Near the rendezvous, Hanumān’s roar spreads in all directions, signaling his approach to the waiting Vānara companions.
Leadership and reassurance: his signal conveys certainty and lifts the anxiety of those awaiting news.
