सप्तपञ्चाशः सर्गः — Hanumān’s Return, Roar of Success, and the Announcement “Sītā Seen”
ये तु तत्रोत्तरे तीरे समुद्रस्य महाबलाः।।।।पूर्वं संविष्ठिताश्शूरा वायुपुत्रदिदृक्षवः।महतो वातनुन्नस्य तोयदस्येव गर्जितम्।।।।शुश्रुवुस्ते तदा घोषमूरुवेगं हनूमतः।
ye tu tatrottare tīre samudrasya mahābalāḥ |
pūrvaṃ saṃviṣṭitāḥ śūrā vāyuputra-didṛkṣavaḥ ||
mahato vātanunnasya toyadasyeva garjitam |
śuśruvus te tadā ghoṣam ūruvegaṃ hanūmataḥ ||
Then those brave, mighty vānaras, already waiting on the ocean’s northern shore and yearning to behold Vāyu’s son, heard Hanumān’s roar—like the thunder of a great rain-cloud driven by wind—born of the tremendous speed and force of his rushing thighs.
Thereafter the brave and powerful monkeys waiting on the northern shore of the ocean for the arrival of the son of the Wind-god, heard the roar and thundering sound of the stormy cloud produced by the sweeping motion of Hanuman's thighs propelled by the speed of his movement.
Dharma here is steadfast commitment to one’s entrusted mission: Hanumān’s energetic return-signal implies truthful completion of duty, restoring rightful hope to the waiting community.
After Hanumān’s work in Laṅkā, the vānaras stationed on the ocean’s northern shore perceive his approach by the thunder-like sound produced by his swift movement.
Vīrya (heroic energy) and niṣṭhā (steadfastness): Hanumān’s powerful, purposeful motion communicates confidence and success.
