Shloka 5.43.5
चैत्यप्रासाद-विध्वंसः (Destruction of the Chaitya Palace and Hanuman’s Proclamation)
संप्रधृष्य च दुर्धर्षं चैत्यप्रासादमुत्तमम्।हनुमान्प्रज्वलन्लक्ष्म्या पारियात्रोपमोऽभवत्।।।।
saṁpradhṛṣya ca durdharṣaṁ caityaprāsādam uttamam |
hanumān prajvalan lakṣmyā pāriyātropamo 'bhavat ||
After overpowering and wrecking that excellent, hard-to-assail shrine-palace, Hanumān blazed with splendor, appearing like the Pariyātra mountain.
Having destroyed the fine palace building, the indomitable Hanuman was blazing with glory like the mountain Pariyatra. (one of the seven Kula mountains viz., Mahendra, Malaya, Sahya, Shuktiman, Riksha, Vindhya and Pariyatra)
Dharma here is expressed as steadfast service to a righteous cause: Hanumān’s force is not mere destruction, but purposeful action undertaken for Rāma’s mission and the recovery of Sītā.
In Laṅkā, after causing havoc among the rākṣasas’ strongholds, Hanumān overpowers a prominent shrine-palace structure and is described as blazing with heroic radiance.
Tejas (radiant power) joined with courage—Hanumān’s fearlessness and commanding presence, portrayed through the mountain comparison.
