लक्ष्मण-प्राणरक्षा: (Lakshmana’s Revival by the Herb-Mountain)
इत्येवमुक्तोहनुमान्गत्वाचौषथिपर्वतम् ।।।।चिन्तामभ्यगमछ्रचीमानजानं स्ता महौषधीः ।
ityevamukto hanumān gatvā cauṣadhiparvatam | cintāmabhyagamacchrīmānajānaṃstā mahauṣadhīḥ ||
Thus addressed, the glorious Hanumān went to the Mountain of Herbs. Yet, unable to identify those particular great herbs, he fell into deep thought.
Sushena having said so, glorious Hanuman set out to the mountain of herbs. Not able to recognise the herbs he thought over.
Despite reaching the Oshadhiparvata, Hanuman could not distinguish the specific medicinal herbs required from the ordinary plants, causing him anxiety about fulfilling his duty (Dharma) to save Lakshmana and the Vanaras.
It highlights Hanuman's divine capability and grace, suggesting that despite the temporary obstacle of not recognizing the herbs, his glory and dedication to Rama's work would eventually lead to a solution.
