Valmiki Ramayana Aranya Kanda Sarga 25 Shloka 13

घोरैः by the dreadful, प्रहरणै by weapons, तैः by those, भिन्नगात्रः his limbs being hit, सः रामः that Rama, प्रदीपैः by the glowing, बहुभिः by many, वज्रैः by thunderbolts, महाचल इव like the great mountain, न विव्यथे was not hurt.

Rama remained unhurt like a great mountain struck by many glowing thunderbolts. He felt no pain even though his limbs were hit by the dreadful weapons.
